[0050] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0051] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can refer to the same reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not in itself indicate a relationship between the various embodiments and / or settings discussed.

[0052] For the convenience of description, spatial relative terms can be used in the text to describe the relative positional relationship or movement of one element or feature with respect to another element or feature as shown in the figure, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" other elements or features will be subsequently oriented as "above" or "above" other elements or features. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0053] The present disclosure relates to a multi-purpose printer, which is particularly designed to meet various needs such as advertising production, art reproduction, and industrial manufacturing identification. The printer realizes wide application scenario adaptability through flexible modular design. As shown in Figures 1-6 The printer includes a rack 1, a first movement mechanism 2, a second movement mechanism 3, and a driving mechanism 4, which cooperate together to ensure the high efficiency, stability, and multifunctionality of the printer.

[0054] It should be noted that in one embodiment, the second movement mechanism 3 can be directly used to place the printed object. In one embodiment, as shown in Figure 1 The printer further includes a printing platform 7, a nozzle 8, a housing 9, an ink cartridge 5 disposed on the housing 9, etc. The printing platform 7 is disposed on the side of the second movement mechanism 3 away from the first movement mechanism 2, and moves synchronously with the second movement mechanism 3, and the printing platform 8 is used to place the printed object. The nozzle 8 is disposed on the rack 1 and is in sliding connection with the rack 1, and the nozzle 8 moves along the second direction of the printer, and the second direction of the printer (refer to the X-axis shown in Figure 2 The first direction of the printer (refer to the Y-axis shown in Figure 2The Y-axis) is perpendicular. Ink cartridge 5 and the like are used to contain ink and are in communication with the inkjet head 8. The frame 1 is used as a basic structure to provide stable support for the entire printer. The frame 1 can be moved in the height direction within the housing 9, and the frame 1 can be raised and lowered by using a slot structure and a lifting mechanism, so as to change the relative position of the frame 1 and the inkjet head 8, thereby meeting different printing requirements.

[0055] The first movement mechanism 2 is a basic movement component of the printer and is responsible for realizing the movement stroke in the first direction (refer to the Y-axis shown in the figure). The first movement mechanism 2 can be, but is not limited to, connected to the frame 1 by using a high-precision guide rail and a slider combination, so as to ensure smooth movement and accurate positioning. The driving part of the first movement mechanism 2 uses a servo motor or a stepper motor to transmit power to the first movement mechanism 2, so that the first movement mechanism 2 can reciprocate relative to the frame 1 in the first direction. Figure 2

[0056] The second movement mechanism 3 is arranged on the side of the first movement mechanism 2 away from the frame 1 in the height direction of the printer (refer to the Z-axis shown in the figure), that is, the second movement mechanism 3 is arranged above the first movement mechanism 2, and is used to realize the same direction (Y-axis direction) movement stroke as the first movement mechanism 2, that is, the second movement mechanism 3 can reciprocate relative to the first movement mechanism 2 in the first direction. The second movement mechanism 3 can be, but is not limited to, also connected to the first movement mechanism 2 by using a high-precision guide rail and a slider combination, but it is designed to be more compact to meet the requirement of being installed above. The driving part of the second movement mechanism 3 also uses a servo motor or a stepper motor, but the movement speed and acceleration thereof can be independently adjusted according to the requirement of the printing task. The specific structure of the printing platform 7 is subject to the actual situation, and is not limited herein. Figure 2

[0057] The driving mechanism 4 is a power source, which is responsible for driving the first movement mechanism 2 to reciprocate relative to the frame 1 in the first direction of the printer, so as to realize the movement of the first movement mechanism 2. On the other hand, the driving mechanism 4 is responsible for driving the second movement mechanism 3 to reciprocate relative to the first movement mechanism 2 in the first direction of the printer. The second movement mechanism 3 is separably connected to the printing platform 7, so that when the driving mechanism 4 drives the second movement mechanism 3, the printing platform 7 can move synchronously with the second movement mechanism 3. The second movement mechanism 3 can be separably connected to the printing platform 7 by using a clamp, a jig or a locking mechanism, and the specific connection manner is subject to the actual situation. The driving mechanism 4 can be provided with an encoder or a grating ruler and the like position feedback element, so as to ensure the accuracy and stability of the movement. The position of the driving mechanism 4 is not limited in the application, and in one embodiment, the driving mechanism 4 is arranged on the frame 1, in one embodiment, the driving mechanism 4 is arranged on the first movement mechanism 2, and in one embodiment, the driving mechanism 4 is arranged on the second movement mechanism 3. ​​

[0058] To achieve a longer movement stroke and higher stability, the movement strokes of the first movement mechanism 2 and the second movement mechanism 3 can be superimposed, and the second movement mechanism 3 moves when the first movement mechanism 2 moves along the Y-axis direction. This step-by-step moving way not only guarantees the length requirement of the stroke in the first direction, but also realizes the stable connection of the movement mechanism.

[0059] The first movement mechanism 2 can have a first movement speed, and the second movement mechanism 3 can have a second movement speed, which can be the same or different to meet different printing needs. When the first movement speed and the second movement speed are different, the flexibility of the printer can be further improved, and the printing range can be flexibly adjusted. By adjusting the speed ratio of the two movement mechanisms, the printing speed and precision can be flexibly controlled to meet the needs of various printing tasks.

[0060] The printer in the embodiment realizes the superimposed state of the movement stroke through flexible modular design, independent movement mechanism and driving control. The entire stroke of the Y-axis movement is divided into the first movement mechanism 2 and the second movement mechanism 3 arranged above and below, and the stroke superposition is realized by using the space in the height direction. Compared with the related art, the overall length of the Y-axis is reduced, and the overall stability is further increased. The first movement mechanism 2 has a first movement stroke, and the second movement mechanism 3 has a second movement stroke, and the movement speeds thereof can be different, the strokes can be superimposed, and the application scenarios and printing range of the printer are increased.

[0061] In the embodiment, as shown in Figures 2-6 The first movement mechanism 2 includes a movement part 21 movably arranged on the rack 1, the second movement mechanism 3 is movably arranged on the movement part 21, and the driving mechanism 4 is arranged on the movement part 21. The movement part 21 provides a stable foundation for connecting and supporting other components, which is usually made of high-strength and corrosion-resistant materials to ensure the reliability and stability during long-term use.

[0062] The movement part 21 can be a multi-plate support structure to support or fix corresponding components. For example, the movement part 21 includes a first sub-movement part 211 and a second sub-movement part 212. The second sub-movement part 212 and the first sub-movement part 211 can be a split structure to realize assembly connection and improve the flexibility of the movement part 21, or can be an integral structure to improve the reliability during connection and realize synchronous movement. The first sub-movement part 211 can be a support bottom plate, and the second sub-movement part 212 can be a side plate, which together provide a mounting platform for the driving mechanism 4. The first sub-movement part 211 is movably connected with the second movement mechanism 3.

[0063] The first movement mechanism 2 is further provided with a guide structure to limit the movement direction of the first movement mechanism 2 or the second mechanism 3, so as to move in the first direction.

[0064] In some embodiments, the first movement mechanism 2 comprises a first guide 22 fixedly connected with the movement part 21, so as to improve the reliability during connection. The first guide 22 comprises a first guide support 221 and a first guide through hole 222 formed in the first guide support 221, which is a channel structure penetrating through the first guide support 221. The first guide 22 is arranged on the movement part 21 through the first guide through hole 222 and is in sliding connection with the rack 1. The first guide 22 is arranged to limit the movement direction of the first movement mechanism 2, so that the first movement mechanism 2 moves reciprocatingly in the first direction of the printer. In this embodiment, the first guide 22 can be two, which are symmetrically arranged in the first direction of the printer, so as to realize the stable movement of the first movement mechanism 2.

[0065] In some embodiments, the first movement mechanism 2 comprises a second guide 23 fixedly connected with the movement part 21, so as to improve the reliability during connection. The second guide 23 comprises a second guide support 231 and a second guide through hole 232 formed in the second guide support 231, which is a channel structure penetrating through the second guide support 231. The second guide 23 is arranged on the movement part 21 through the second guide through hole 232 and is in sliding connection with the second movement mechanism 3. The second guide 23 is arranged to limit the movement direction of the second movement mechanism 3, so that the second movement mechanism 3 moves reciprocatingly in the first direction of the printer. In this embodiment, the second guide 23 can be two, which are symmetrically arranged in the first direction of the printer, so as to improve the stability of the second movement mechanism 3 during movement.

[0066] In some embodiments, the first movement mechanism 2 comprises a first guide 22 and a second guide 23, and the second movement mechanism 3 cooperates with the first movement mechanism 2 to complete a complex printing task. In this embodiment, the first guide 22 can be two, which are symmetrically arranged in the first direction of the printer, and the second guide 23 can also be two, which are symmetrically arranged in the first direction of the printer, so as to improve the stability during movement. The first guide 22 and the second guide 23 located on the same side can be arranged in an upper and lower interval and staggered.

[0067] Of course, it can be understood that the first guide 22 and the second guide 23 arranged in an upper and lower interval can also be arranged without staggering. Different arrangement modes can meet the first movement mechanism 2 and the second movement mechanism 3 of different sizes. The arrangement in an upper and lower interval can ensure a certain gap between the first movement mechanism 2 and the second movement mechanism 3, avoid mutual interference, and ensure the normal movement of each other. The specific arrangement mode is subject to the actual situation.

[0068] The first guide 22 and the second guide 23 not only limit the movement direction of the first movement mechanism 2 and the second movement mechanism 3, but also ensure their stability and accuracy during reciprocating movement. Through the guidance of the guides, the first movement mechanism 2 and the second movement mechanism 3 can move along a predetermined path, thereby achieving accurate printing work.

[0069] In the present embodiment, as shown in Figures 2-6 The driving mechanism 4, as the core power component of the printer, is designed to ensure that the first movement mechanism 2 and the second movement mechanism 3 can move efficiently, stably and synchronously, while meeting the needs of different movement speeds of the two in different printing ranges.

[0070] The driving mechanism 4, for example, includes a first driving part 41, a first transmission part 42 and a second transmission part 43, which are respectively connected with the first driving part 41 so that the first driving part 41 applies driving force to the first transmission part 42 and the second transmission part 43.

[0071] The first transmission part 42 and the second transmission part 43 are both mounted on the second sub-movement part 212 of the movement part 21, which provides a mounting platform for the first transmission part 42 and the second transmission part 43. The second sub-movement part 212 is designed with stability and load-bearing capacity to ensure that the transmission parts can run smoothly and efficiently. The housing of the first driving part 41 can be fixedly connected with the first sub-movement part 211, and its driving shaft can be rotatably passed through the second sub-movement part 212 and connected with the first transmission part 42 and the second transmission part 43 respectively. Alternatively, the housing of the first driving part 41 can be fixedly connected with the second sub-movement part 212, and its driving shaft can be rotatably passed through the second sub-movement part 212 and connected with the first transmission part 42 and the second transmission part 43 respectively. Alternatively, in order to further improve stability, the housing of the first driving part 41 can be fixedly connected with the first sub-movement part 211 and the second sub-movement part 212 respectively, and its driving shaft can be rotatably passed through the second sub-movement part 212 and connected with the first transmission part 42 and the second transmission part 43 respectively.

[0072] The first movement mechanism 2, as the support structure of the entire driving mechanism 4, is made of high-strength and lightweight materials to ensure sufficient rigidity and stability. The first driving part 41 is the power source of the driving mechanism 4, responsible for providing stable driving force. The first driving part 41, for example, adopts a high-performance servo motor, which has the characteristics of fast response speed, high control accuracy and large output torque, and can meet the needs of speed and force for different printing tasks. The servo motor is connected with the first transmission part 42 and the second transmission part 43 to realize power transmission.

[0073] The first transmission part 42 transmits the power of the first driving part 41 to the first movement mechanism 2. Exemplarily, the first transmission part 42 is mounted on the second sub-movement part 212 of the first movement mechanism 2, the first transmission part 42 is in driving connection with the frame 1, and the first driving part 41 drives the first movement mechanism 2 to reciprocate along the first direction of the printer relative to the frame 1 through the first transmission part 42.

[0074] The second transmission part 43 transmits the power of the first driving part 41 to the second movement mechanism 3. Exemplarily, the second transmission part 43 is arranged on the second sub-movement part 212 of the first movement mechanism 2, the second transmission part 43 is in driving connection with the second movement mechanism 3, and the first driving part 41 drives the second movement mechanism 3 to move synchronously with the first movement mechanism 2 through the second transmission part 43.

[0075] The movement speed of the first movement mechanism 2 and the movement speed of the second movement mechanism 3 are different to adapt to different printing ranges. The first transmission part 42 and the second transmission part 43 can set the transmission ratio or the lead to different values, so that the first movement mechanism 2 and the second movement mechanism 3 can obtain different movement speeds under the same driving force. In addition, through the precise control of the rotation speed and rotation direction of the servo motor by the control algorithm, the independent adjustment of the movement speed and acceleration of the two movement mechanisms can be further realized.

[0076] Exemplarily, the first transmission part 42 includes a first main transmission wheel 421, a first transmission belt 422, and two first driven transmission wheels 423, which work together to ensure that the first movement mechanism 2 can be smoothly and continuously transmitted from one position to another position.

[0077] The first main transmission wheel 421 is a driving wheel and is directly connected with the first driving part 41, that is, the first main transmission wheel 421 is fixedly sleeved on the output shaft of the first driving part 41. When the first driving part 41 is started, its rotary power will be directly transmitted to the first main transmission wheel 421, thereby driving it to rotate.

[0078] The two first driven transmission wheels 423 are rotatably mounted on the second sub-movement part 212 of the first movement mechanism 2. In order to ensure the stability and smooth rotation of the first driven transmission wheel 423, for example, the first driven transmission wheel 423 is rotatably sleeved on a first connecting shaft body 4231, and the first connecting shaft body 4231 is fixedly connected with the second sub-movement part 212 of the first movement mechanism 2 to realize the stability of the first driven transmission wheel 423. The two first driven transmission wheels 423 are arranged on the two sides of the first main transmission wheel 421 to form a triangular layout, which helps to enhance the stability and tension of the first transmission belt 422.

[0079] The first transmission belt 422 is wound around the first main transmission wheel 421 and two first driven transmission wheels 423, for example, from one first driven transmission wheel 423, passes the first main transmission wheel 421, and finally reaches the other first driven transmission wheel 423, which ensures that the first transmission belt 422 can maintain proper tension and stability during operation. In order to further ensure the stable operation of the first transmission belt 422, it is designed to form a certain pressing state after winding. This pressing state can be achieved by adjusting the relative position between the first main transmission wheel 421 and the first driven transmission wheel 423 or the tension of the transmission belt.

[0080] The two ends of the first transmission belt 422 are fixedly connected with the rack 1, and the middle part of the first transmission belt 422 is wound around the first main transmission wheel 421 and the two first driven transmission wheels 423, so as to drive the first movement mechanism 2 to move through the first driving part 41 and the first transmission part 42. For example, the two ends of the first transmission belt 422 are respectively provided with a belt fixing seat 4221, and the first transmission belt 422 is fixedly connected with the rack 1 through the belt fixing seat 4221. When the first driving part 41 drives the first main transmission wheel 421, the first transmission belt 422 moves on the first main transmission wheel 421 and the first driven transmission wheel 423, thereby driving the first movement mechanism 2 to move together.

[0081] In the present example, the second transmission part 43 includes a second main transmission wheel 431, a second transmission belt 432, and two second driven transmission wheels 433, which cooperate together to ensure that the materials or components can be smoothly and efficiently transmitted from one position to another position and synchronously moved with the second movement mechanism 3.

[0082] The second main transmission wheel 431 is the driving wheel of the second transmission part 43, and its outer diameter size is designed to be larger than that of the first main transmission wheel 421, so that the number of teeth is different, thereby adjusting the movement speed of the transmission belt and effectively improving the transmission efficiency and carrying capacity of the second transmission part 43.

[0083] The second main transmission wheel 431 is connected with the driving shaft of the first driving part 41 to receive the rotary power from the first driving part 41. When the first driving part 41 is started, the rotary power will be directly transmitted to the second main transmission wheel 431, thereby driving it to rotate.

[0084] The two second driven transmission wheels 433 are rotatably mounted on the second sub-motion part 212 of the first motion mechanism 2, for example, arranged on the second sub-motion part 212 of the first motion mechanism 2 through a second connecting shaft body 4331. The two second driven transmission wheels 433 are arranged on the two sides of the second main transmission wheel 431, so that a triangular layout is also formed between the second driven transmission wheel 433 and the second main transmission wheel 431. The second transmission belt 432 is arranged around the second main transmission wheel 431 and the two second driven transmission wheels 433, and the two ends of the second transmission belt 432 are connected with the second motion mechanism 3. It can be understood that the second transmission part 43 is arranged in the same or similar manner as the first transmission part 42, and will not be repeated here.

[0085] In the embodiment, the first main transmission wheel 421 and the second main transmission wheel 431 are arranged with different outer diameters, which directly affects the number of teeth. Since the number of teeth is proportional to the outer diameter, the number of teeth of the second main transmission wheel 431 also increases accordingly. The increase in the number of teeth means that the second transmission belt 432 is longer driven by the second main transmission wheel 431 per revolution at the same speed, thereby adjusting the movement speed of the second transmission belt 432.

[0086] When the first driving part 41 is started, the first main transmission wheel 421 and the second main transmission wheel 431 are driven to rotate at the same angular speed, respectively driving the first motion mechanism 2 and the second motion mechanism 3 to move in the same direction. Since the number of teeth of the first main transmission wheel 421 and the second main transmission wheel 431 is different, the movement speed of the first motion mechanism 2 and the second motion mechanism 3 is different, but the stroke can be superimposed.

[0087] The first transmission part 42 and the second transmission part 43 can be arranged in the height direction to achieve the stacking effect between the first transmission part 42 and the second transmission part 43 in the height direction. On the one hand, the first motion mechanism 2 and the second motion mechanism 3 can move independently without interfering with each other. On the other hand, the trajectory of the transmission belt is changed to ensure normal movement, and the movement stroke is superimposed by using the space in the height direction, reducing the length in the first direction, which can effectively improve the overall stability of the printer.

[0088] It should be noted that the first transmission part 42 and the second transmission part 43 can also be implemented in other ways. For example, the first transmission part 42 includes a chain (not shown in the figure) and a plurality of gears (not shown in the figure). The plurality of gears are arranged in the same manner as the first main transmission wheel 421 and the two first driven transmission wheels 423, and the chain is arranged in the same manner as the first transmission belt 422. Here, it will not be repeated, as long as the transmission of driving force can be achieved. The second transmission part 43 can also be a chain and a plurality of gears to achieve the transmission of driving force.

[0089] In the present embodiment, as shown in Figures 2-6 The frame 1 includes a frame 11 and a first guide shaft 12, the frame 11 serving as the main part of the frame 1 for carrying and conveying materials or components, the frame 11 being a solid and light structure to achieve the lightness of the printer, and the frame 11 being able to provide stable support for the first movement mechanism 2 and the second movement mechanism 3.

[0090] The frame 11 is connected with the first guide shaft 12 to play a role of supporting and guiding movement. The first guide shaft 12 is in sliding connection with the first guide 22 to ensure that the first movement mechanism 2 can move back and forth along the predetermined path of the first guide shaft 12. The first guide shaft 12 is, for example, cylindrical, and the first guide 22 is a through hole formed on the first support body 213 and movably sleeved on the first guide shaft 12. Alternatively, the first guide shaft 12 is, for example, T-shaped, and the first guide 22 is, for example, provided with a T-shaped slot, and the two are in sliding connection.

[0091] In the present embodiment, as shown in Figures 2-6 The second movement mechanism 3 includes a movement platform 31 and a second guide shaft 32, the movement platform 31 being fixedly connected with the second guide shaft 32, and the second guide shaft 32 being in sliding connection with the second guide 23. The movement platform 31 is connected with the second conveying part 43, and the first driving part 41 drives the movement platform 31 and the second guide shaft 32 to move along the second guide 23 through the second conveying part 43.

[0092] It should be noted that the structure and function of the above-mentioned second movement mechanism 3 are the same as or similar to those of the first movement mechanism 2, but can be adjusted according to specific movement requirements, and the actual situation shall prevail.

[0093] The printer proposed in the present embodiment is driven by a first driving part 41 to stably and without deviation move back and forth along the respective guides, which not only improves the stability and reliability of the system, but also provides strong support for the accurate conveying of materials or components.

[0094] In order to ensure the stability and reliability of the driving mechanism 4, the present embodiment is also equipped with an advanced movement control system and a monitoring system. The movement control system is responsible for receiving control instructions from the printer and accurately controlling the operation of the servo motor according to the instructions. The monitoring system monitors the working state of the driving mechanism 4 in real time, including the temperature, current, speed and other parameters of the motor, as well as the wear and looseness of the transmission mechanism. Once an abnormal condition is found, the system will immediately issue an alarm and take appropriate protective measures.

[0095] In actual application, especially when processing large size platform plate, the printer in the present disclosure has certain stability. Even if the motion platform size is large, tilting will not occur. In the related art, when the platform plate size is large, the mass and the moment of inertia are correspondingly increased, causing the platform plate to be more easily affected by external factors (such as uneven gravity, uneven ground, driving mechanism error, etc.) when moving in the Y-axis direction, and then tilting. However, in the present disclosure, by arranging the first motion mechanism 2 and the second motion mechanism 3 upward and downward, the longitudinal space is used, not only the use of the transverse space is reduced, avoiding interference with the surrounding equipment, improving the safety of the printer itself, but also the superposition of the motion stroke can be realized, the overall stability can be improved, the motion mechanism is not easily affected by external factors, the precision and repeatability of the motion mechanism in the moving process are ensured, and the printing efficiency and printing quality of the entire printer are improved.

[0096] In an embodiment of the present application, the to-be-printed object is placed on the second motion mechanism 3 for printing.

[0097] In an embodiment of the present application, as shown in Figures 6-8 The printer further includes a printing platform 7, which is detachably connected with the motion platform 31 of the second motion mechanism 3. The printing platform 7 is arranged on the side of the second motion mechanism 3 away from the first motion mechanism 2, and moves synchronously with the second motion mechanism 3. The printing platform 7 is a structure for placing the to-be-printed object, and the specific shape of the printing platform 7 is not limited to a flat structure. The printing platform 7 can also be a rotating body structure for placing and rotating a cup. It should be noted that the printing platform 7 and the motion platform 31 in the figure are only schematic representations and do not limit the present application. Here, only the relative positional relationship and the mounting position are provided for easy understanding, and the printing platform 7 in actual application can be implemented in other forms, such as a clamping structure, and the specific implementation is subject to the actual situation.

[0098] Exemplarily, the printing platform 7 can be positioned and connected with the second motion mechanism 3 through a positioning structure. For example, one of the motion platform 31 of the second motion mechanism 3 and the printing platform 7 is provided with a positioning hole, and the other is provided with a positioning protrusion. The positioning protrusion and the positioning hole are connected through plug-in connection, so as to stably mount the printing platform 7. The implementation is simple and easy to operate.

[0099] Alternatively, the printer further includes a locking device 6, and the printing platform 7 is detachably connected with the motion platform 31 through the locking device 6, so as to improve the stability when the printing platform 7 is connected with the motion platform 31. The locking device 6 is further explained and described below, so as to better understand the present embodiment.

[0100] The locking device 6 is used to realize locking and dismounting of the printing platform 7 and the moving platform 31. The locking device 6 includes a first locking part 61 and a second locking part 62, for example. The first locking part 61 is provided with a locking groove 611. In an embodiment, the first locking part 61 is arranged on the printing platform 7, and the second locking part 62 is arranged on the moving platform 31. In an embodiment, the second locking part 62 is arranged on the printing platform 7, and the first locking part 61 is arranged on the moving platform 31. This embodiment takes the second locking part 62 arranged on the printing platform 7 and the first locking part 61 arranged on the moving platform 31 as an example for explanation and description.

[0101] When the printing platform 7 is mounted to the moving platform 31, part of the structure of the second locking part 62 can be accommodated in the locking groove 611, so as to realize the locking state of the locking device 6. The first locking part 61 is arranged to rotate relative to the second locking part 62, so that the locking device 6 is in a locked state of fixedly connecting the printing platform 7 and the moving platform 31, or in a released state of unlocking the printing platform 7 and the moving platform 31. When the locking device 6 is in the released state, the printing platform 7 and the moving platform 31 can be separated.

[0102] In an embodiment, the first locking part 61 and the second locking part 62 are threadedly connected. Part of the structure of the second locking part 62 is accommodated in the locking groove 611 of the first locking part 61. The first locking part 61 is rotated relative to the second locking part 62, so that the locking device 4 is in a locked state of fixedly connecting the printing platform 7 and the moving platform 31, or in a released state of unlocking the printing platform 7 and the moving platform 31.

[0103] In an embodiment, the first locking part 61 is hingedly connected to the moving platform 31. One end of the first locking part 61 is rotatably connected to the moving platform 31, and the other end is detachably connected to the moving platform 31. When it is necessary to fixedly connect the printing platform 7 and the moving platform 31, first, the other end of the first locking part 61 is separated from the moving platform 31, and part of the structure of the second locking part 62 is accommodated in the locking groove 611 of the first locking part 61. Then, the first locking part 61 is rotated, so that the other end of the first locking part 61 is fixedly connected to the moving platform 31, thereby limiting the second locking part 62 in the locking groove 611.

[0104] The printer in the embodiment is provided with a printing platform 7 arranged on the side of the moving platform 31 away from the rack 1 and detachable from the moving platform 31 through the locking device 4. Specifically, the locking device 4 includes a first locking portion 41 and a second locking portion 42. The first locking portion 41 is rotatable relative to the second locking portion 42 to switch between the locking state and the release state, thereby realizing the detachable connection of the printing platform 7 and the moving platform 31, meeting the requirements of different application scenarios, improving the flexibility and applicability of the printer, and improving the utilization rate of the printer. Moreover, the moving platform 31 and the printing platform 7 are assembled and connected, and the first locking portion 61 is rotated to change the relative positions of the first locking portion 61 and the second locking portion 62, thereby realizing the locking state or the release state of the locking device 6, achieving the purpose of quick disassembly or quick assembly, and effectively improving the installation efficiency.

[0105] In the embodiment, the first locking portion 61 includes a locking wheel 613 rotatably connected with the moving platform 31. The locking wheel 613 is formed with a locking groove 611 for accommodating part of the structure of the second locking portion 62.

[0106] First example

[0107] The locking groove 611 is, for example, an arc-shaped groove, and the second locking portion 62 is, for example, an arc-shaped body. When the second locking portion 62 is rotated relative to the first locking portion 61, the arc-shaped groove corresponds to the arc-shaped body, so that the arc-shaped body can be inserted into the arc-shaped groove, thereby realizing the locking state between the first locking portion 61 and the second locking portion 62; conversely, moving the arc-shaped body out of the arc-shaped groove can realize the release state between the first locking portion 61 and the second locking portion 62.

[0108] In operation, the first locking portion 61 can also be rotated relative to the second locking portion 62 to make the arc-shaped body correspondingly inserted into or moved out of the arc-shaped groove, thereby quickly realizing the locking or release of the printing platform 7 and the moving platform 31. This simple operation method does not require the use of complex tools or complicated steps, greatly improving the installation and disassembly efficiency of the printer and saving time and cost.

[0109] This design enables a single person to easily complete the disassembly and assembly of the printing platform 7. In the case of frequent replacement of the printing platform 7 to adapt to different printing tasks, the operator does not need the assistance of others and can quickly and independently complete the operation, improving the autonomy and flexibility of the work.

[0110] When the arc-shaped body is inserted into the arc-shaped groove, the arc-shaped structures between the two can closely fit, forming a larger contact area and friction. This close fitting can effectively prevent the printing platform 7 from loosening or shaking during printing, ensuring the accuracy and quality of printing. Even when the printer is moving at high speed or under a large external force, the locking device 6 can ensure that the printing platform 7 remains relatively stable in connection with the moving platform 31.

[0111] The arc-shaped design can better adapt to various forces and vibrations generated during printing. Under different printing tasks and environmental conditions, the locking device 6 can provide reliable locking force, ensuring the stable operation of the printer and reducing the risk of printing failure or quality problems caused by loosening of the printing platform 7.

[0112] This locking method allows the printer to quickly adapt to different application scenarios. For example, in different printing scenarios, different sizes or materials of printing platforms 7 may be required. Through this locking device 6, the operator can quickly disassemble and install different types of printing platforms 7 to meet diverse printing needs. At the same time, in scenarios such as art reproduction that require high printing accuracy, reliable locking performance can also ensure printing quality.

[0113] As an important module of the printer, the printing platform 7 can be easily combined and replaced with other modules through this convenient locking method. In the future, if the printer needs to be functionally expanded or upgraded, only the corresponding printing platform 7 module needs to be replaced, without the need for large-scale changes to the entire printer, providing strong support for the modular design of the printer.

[0114] Second Example

[0115] The locking slot 611 is, for example, circular in shape, and the locking wheel 613 has an opening 612 that communicates with the locking slot 611, and part of the structure of the second locking portion 62 can pass through the opening 612 into the locking slot 611. At this time, by rotating the first locking portion 61, the relative position of the first locking portion 61 and the second locking portion 62 is changed, realizing the locking state or release state of the locking device 6.

[0116] For example, the relative position between the opening 612 and the second locking portion 62 changes, i.e., the opening 612 and the second locking portion 62 have a first relative position and a second relative position. When the opening 612 is upward, the first relative position between the opening 612 and the second locking portion 62 is formed, and when the opening 612 is offset from the above position, i.e., in other directions, it can be considered as the second relative position between the opening 612 and the second locking portion 62. Since the printing platform 7 is along the height direction of the printer (refer to FIG. 1), the relative position between the opening 612 and the second locking portion 62 is the relative position between the opening 612 and the second locking portion 62 in the horizontal direction. Figure 2The second locking portion 62 can be mounted or dismounted through the notch 612, and therefore, as long as the notch 612 is staggered in the height direction, the second locking portion 62 can be shielded from disengaging from the locking groove 611.

[0117] When the notch 612 and the second locking portion 62 are in the first relative position, i.e., the notch 612 is upward, the locking device 6 is in the released state, and the printing platform 7 can be conveniently dismounted or mounted. When the notch 612 and the second locking portion 62 are in the second relative position, the locking device 6 is in the locked state, and the notch 612 and the locking groove 611 form an arc-shaped plate for the first locking portion 61, which can constrain the second locking portion 62, so that the printing platform 7 is stably mounted on the moving platform 31.

[0118] The locking groove 611 is an area inside the first locking portion 61 for cooperating with the locking shaft body 622, and the shape, size and position thereof are matched with the locking shaft body 622. For example, the locking groove 611 is eccentric circular, so that the distance between the center position and the inner side wall of the locking groove 611 is different. The eccentric design can be achieved by changing the thickness of the arc-shaped plate and the distance between the center position and the inner side wall of the locking groove 611. For example, the two sides of the notch 612 are the starting end, and the position opposite to the notch 612 is the terminal end. From the starting end to the terminal end, the thickness of the arc-shaped plate gradually increases. When the locking device 6 is in the unlocked state, the notch 612 is upward, and when the locking device 6 is in the locked state, the first locking portion 61 can be rotated by 180°, so that the notch 612 is downward, and at this time, the second locking portion 62 can abut against the inner side wall of the locking groove 611 to improve the stability during locking.

[0119] The first locking portion 61 is arranged in the moving platform 31, and the moving platform 31 is provided with a first avoiding through hole (not shown in the figure). This structure design has multiple advantages. On the one hand, the first avoiding through hole provides an avoiding space for the second locking portion 62, so as to ensure that the second locking portion 62 can smoothly pass through the notch 612 to realize the locking and releasing functions. On the other hand, the first locking portion 61 is arranged in the moving platform 31, so as to avoid being directly exposed to the external environment, effectively preventing dust, sundries and the like from eroding and damaging the first locking portion 61, and prolonging the service life of the locking device 6. At the same time, this design also improves the overall flatness of the printer, so that the printer is more stable during operation, and the vibration and noise generated due to the uneven structure are reduced.

[0120] The locking device 6 can realize the switching between the locking and releasing states by rotating the first locking part 61 to change the relative position of the first locking part 61 and the second locking part 62. When the gap 612 is upward in the first relative position, the locking device 6 is in the releasing state, and the printing platform 7 can be conveniently disassembled or installed without complex tools or cumbersome steps, which greatly improves the operation efficiency. This simple and convenient operation mode reduces the requirement for the professional skills of the operator and reduces the operation time and labor cost.

[0121] The locking groove 611 is accurately matched with the second locking part 62, and the locking groove 611 can be designed as an eccentric circle, and the eccentric design is realized by using the thickness change of the arc-shaped plate. Specifically, the thickness of the inner side wall of the locking groove 611 near the gap 612 is smaller than the thickness of the inner side wall of the locking groove 611 away from the gap 612. In the locking state, the first locking part 61 is rotated to make the gap 612 face the direction close to the rack 1, and the second locking part 62 abuts against the inner side wall of the locking groove 611. This design increases the contact area and friction force between the first locking part 61 and the second locking part 62, effectively improves the stability of the locking state. The arc-shaped plate restricts the second locking part 62, so that the printing platform 7 can be stably installed on the moving platform 31, avoiding problems such as decrease of printing precision and model deformation caused by platform loosening during printing, and improving the printing quality and reliability. Compared with the structure in which the thickness of the inner side wall of the locking groove 611 is consistent at each position, the operation process of the present scheme is more labor-saving, the second locking part 62 is easily put into the locking groove 611, and the connection stability in the locking state is improved.

[0122] The structure design of the locking device 6 fully utilizes the limited space. The layout of the locking groove 611, the gap 612 and the first avoiding through hole is compact and reasonable, which maximally reduces the volume and occupied space of the locking device 6 under the premise of ensuring the locking function. This not only makes the overall structure of the printer more compact, facilitating installation and carrying, but also provides more space for the layout of other components of the printer, which is conducive to the miniaturization and integration development of the printer.

[0123] In the present embodiment, the number of the second locking parts 62 is consistent with and correspondingly arranged with the number of the locking wheels 613 of the first locking part 61, which ensures the cooperative work between the components. The second locking part 62 includes a support body 621 and a locking shaft body 622, the locking shaft body 622 is connected with the printing platform 7 through the support body 621, and at least part of the structure of the locking shaft body 622 is accommodated in the locking groove 611.

[0124] The support body 621 is firmly fixed on the printing platform 7 by means of bolts, screws, welding, etc., providing a stable support foundation for the locking shaft body 622, ensuring that the locking shaft body 622 is stable and reliable in position during the locking process. The support body 621 adopts a spring design, which can produce a certain deformation during installation, allowing the locking shaft body 622 to smoothly enter the locking groove, avoiding installation difficulties caused by limited installation space, and improving installation efficiency and success rate.

[0125] When the locking device 6 is in the locked state, the locking shaft body 622 can abut against the inner side wall of the locking groove 611, improving the reliability of the locking between the first locking part 61 and the second locking part 62.

[0126] In an embodiment of the present application, the second locking part 62 is rotationally connected to the printing platform 7, and the rotation direction of the second locking part 62 relative to the printing platform 7 is the axial direction of the second locking part 62. Specifically, the locking shaft body 622 includes a shaft block 6221, a locking bearing 6222, and a circlip 6223, for example. The modular design of the locking shaft body 622 ensures a stable position during the locking process, effectively reducing the problem of inaccurate locking caused by the locking shaft body 622 shaking or shifting, and improving the locking accuracy and stability.

[0127] The locking bearing 6222 is installed on the shaft block 6221, and its high-precision rolling contact surface can reduce frictional resistance, improve the smoothness and accuracy of the locking process. At the same time, the load-carrying capacity of the locking bearing 6222 also ensures the stability of the locking device 6 when it is subjected to a large load, further improving the locking performance. The locking bearing 6222 abuts against the locking groove 611, and is in the shape of a cylinder to facilitate close fitting with the inner side wall of the locking groove 611.

[0128] By installing the circlip 6223 on the outside of the locking bearing 6222, the locking bearing 6222 can be effectively prevented from coming off the shaft block 6221 due to vibration or external force during operation, not only improving the overall structural strength of the locking shaft body 622, but also ensuring the continuity and reliability of the locking process.

[0129] The modular design of the locking shaft body 622 makes it easy to disassemble and assemble the components. When the locking bearing 6222 is worn or damaged due to long-term use, the user can easily replace the locking bearing 6222 by simply disassembling the circlip 6223, without the need for complex maintenance of the entire locking shaft body 622. This design reduces maintenance costs and improves the service life of the locking device 6.

[0130] The combination of the rotating shaft block 6221, the locking bearing 6222, and the snap spring 6223 makes the locking shaft body 622 have certain versatility and adaptability. By adjusting the model and specification of the locking bearing 6222 and selecting the appropriate size of the snap spring 6223, the locking shaft body 622 can adapt to the needs of different equipment and application scenarios. This design improves the flexibility and market competitiveness of the locking device 6.

[0131] The locking device 6 provided in the embodiment can realize the switching between the locking and releasing states by rotating the first locking part 61, and the operation is simple and convenient. The locking groove 611 is accurately matched with the second locking part 62. The locking groove 611 is set as an eccentric circle, and the thickness of the inner side wall of the locking groove 611 near the aperture 612 is smaller than the thickness of the inner side wall of the locking groove 611 away from the aperture 612. During the rotation of the first locking part 61 relative to the second locking part 62, the distance between the outer surface of the second locking part 62 and the inner wall of the locking groove 611 gradually decreases, which increases the contact area and friction, and improves the locking stability. Compared with the scheme in which the inner side wall of the locking groove 611 has a uniform thickness, the present scheme realizes the labor-saving effect and further improves the operation convenience of the locking device 6. Moreover, the structure of the locking device 6 is compact and reasonable, which effectively reduces the volume and occupied space, and is beneficial to the miniaturization and integration development of the printer. In addition, the locking shaft body 622 adopts a modular design, which is convenient for disassembly and assembly, reduces the maintenance cost, and prolongs the service life. The combination design of the locking shaft body 622 gives it good versatility and adaptability, and further improves the flexibility and market competitiveness of the locking device.

[0132] In other optional embodiments, the present embodiment provides a printer, as shown in the drawings, Figures 7-8 As shown in the drawings, the first locking part 61 of the present embodiment includes a synchronous shaft body 614, and one locking wheel 613 is arranged at each end of the synchronous shaft body 614. At this time, the locking wheel 613 in the present embodiment is provided as two, and the synchronous shaft body 614 can extend along the first direction of the printer or along the second direction of the printer. The present embodiment takes the extension along the first direction of the printer as an example for detailed description.

[0133] The synchronous shaft body 614 is rotatably arranged on the movement platform 31. In order to ensure the stability of the synchronous shaft body 614 during rotation, a first connecting lug (not shown in the drawings) is arranged on the movement platform 31, and the synchronous shaft body 614 rotatably penetrates the first connecting lug. This mounting manner makes the synchronous shaft body 614 maintain good stability during rotation, and reduces the influence on the performance of the locking device 6 caused by unstable rotation. The first connecting lug provides reliable support and positioning for the synchronous shaft body 614, so that the synchronous shaft body 614 can smoothly rotate at the predetermined position.

[0134] The two locking wheels 613 are installed on both ends of the synchronous shaft body 614 in a fixed sleeve manner, which enables the two locking wheels 613 to rotate synchronously by means of the synchronous shaft body 614. When the synchronous shaft body 614 rotates, the two locking wheels 613 at both ends rotate at the same angular velocity, thereby ensuring the consistency of the two locking wheels 613 in action.

[0135] When the locking device 6 performs the locking or releasing operation, the two locking wheels 613 on both sides simultaneously interact with the second locking part 62. Since the two locking wheels 613 rotate synchronously, the force exerted by them on the second locking part 62 is more uniform and stable. Compared with the design of a single locking wheel, the design of the two locking wheels 613 on both sides can effectively reduce the problem of unstable locking caused by uneven force on one side.

[0136] The two locking wheels 613 on both sides make the interaction between the first locking part 61 and the second locking part 62 more stable. After the printing platform 7 is installed on the motion platform 31, the relative position with the motion platform 31 can be more stably maintained, reducing the situation of shaking or displacement of the printing platform 7 caused by unstable locking, and improving the reliability and stability of the entire locking device 6.

[0137] Since the stability of the locking device 6 is enhanced, the printing platform 7 can maintain a more stable state during printing, thereby ensuring the accuracy of the printer during printing. The stable printing platform 7 can ensure that the distance between the print head and the printing medium remains consistent during printing, reducing printing errors caused by platform shaking and improving printing quality.

[0138] The synchronous shaft body 614 is rotatably arranged on the motion platform 31 and stably rotates through the first connecting lug. This structure design is reasonable and compact. It not only improves the working performance of the locking device 6, but also reduces the possible failure points caused by complex structure, thereby reducing the maintenance cost of the printer. At the same time, this design also facilitates the assembly and disassembly of the locking device 6, thereby improving the production efficiency.

[0139] The printer in the embodiment enhances the stability and reliability of the locking device 6 by arranging the locking wheels 613 that rotate synchronously at both ends of the first locking part 61 and optimizing the installation mode of the synchronous shaft body 614, thereby improving the printing accuracy of the printer and optimizing the structural design of the printer, which has significant beneficial effects.

[0140] In other optional embodiments, the first locking part 61 of the embodiment includes a synchronous shaft body 614, a second driving part 615, and a third transmission part 616.

[0141] Two synchronous shaft bodies 614 are symmetrically arranged along the first direction of the printer, the second driving part 615 is connected with the third transmission part 616, and the third transmission part 616 is connected with the two synchronous shaft bodies 614 respectively. One locking wheel 613 is arranged at each end of each synchronous shaft body 614. That is, the four locking wheels 613 are arranged close to the four corner ends of the movement platform 31 to realize multi-point locking and improve the stability of the movement platform 31 during installation, so as to ensure the uniformity of the locking effect. The multi-point locking design makes the printing platform 7 more uniform in stress during locking, reduces the shaking or tilting of the printing platform 7 caused by uneven local stress, and improves the installation precision and stability of the printing platform 7.

[0142] The second driving part 615 is arranged on the movement platform 31, and the second driving part 615 and the two synchronous shaft bodies 614 are connected through the third transmission part 616 to drive the two synchronous shaft bodies 614 to rotate synchronously. The second driving part 615 drives the third transmission part 616 to move in a circular motion, and in turn drives the two synchronous shaft bodies 614 to rotate synchronously, which simplifies the operation difficulty during locking and effectively improves the locking efficiency.

[0143] First example

[0144] The second driving part 615, for example, includes a push hand 6151 and two synchronous wheels 6152, and the third transmission part 616 is, for example, a synchronous belt. The synchronous belt is connected with the push hand 6151 through a belt tensioning adjuster 6161.

[0145] The movement platform 31 is provided with a slide (not shown in the figure), and the push hand 6151 is slidingly arranged in the slide. The user generates driving force by sliding the push hand 6151 along the slide. This design of using the push hand 6151 as a power source greatly simplifies the operation process, reduces the operation difficulty, and enables the user to easily and quickly realize the locking and releasing functions.

[0146] The synchronous belt as the third transmission part 616 is tightly connected with the push hand 6151 through the belt tensioning adjuster 6161, which ensures that the driving force generated by the push hand 6151 can be stably and accurately transmitted to the synchronous belt. The synchronous belt is sleeved on the two synchronous wheels 6152, and the synchronous wheels 6152 are sleeved on the corresponding synchronous shaft bodies 614. When the push hand 6151 slides, it drives the synchronous belt to move in a circular motion, and the rotation of the synchronous wheels 6152 is highly consistent with the movement of the synchronous belt, thereby driving the synchronous shaft bodies 614 to rotate stably. This synchronization mechanism ensures the stability and reliability of the locking device 6 during locking or releasing.

[0147] The setting of the slide not only provides stable guidance for the pusher, but also makes the structure of the entire locking device 6 more compact. In addition, the design of key components such as the synchronous belt and the synchronous wheel 6152 makes them easy to disassemble and replace, reducing maintenance costs and time. The pusher 6151, the synchronous belt and the synchronous wheel 6152 and other key components are made of high-strength, wear-resistant materials, which can withstand large forces and friction, thereby prolonging the service life of the locking device 6. The setting of the belt tensioning adjuster 6161 can also ensure that the synchronous belt always maintains proper tension, avoiding failures and damage caused by slackness or excessive tension.

[0148] Second example

[0149] The second driving part 615 includes a driving body (not shown in the figure) and a driving wheel (not shown in the figure), and the third transmission part 616 is, for example, a chain, which has the same implementation principle and setting mode as the first example described above, and both rely on linear motion to realize the rotation of the synchronous shaft body 614. Here, no longer detailed.

[0150] Alternatively, the second driving part 615 includes, for example, a rotating rod (not shown in the figure) and two rotating wheels (not shown in the figure), and the third transmission part 616 is, for example, a chain. The rotating rod is rotatably arranged on the movement platform 31, and the outer peripheral side wall of the rotating rod is provided with teeth, so that the rotating rod is meshed and connected with the chain. The chain is meshed on the two rotating wheels, and the two rotating wheels are respectively sleeved on the corresponding synchronous shaft body 614.

[0151] The user can generate driving force by rotating the rotating rod, thereby driving the chain to do circular motion. The chain is meshed and connected with the rotating wheel, thereby driving the two synchronous wheels 6152 to rotate. The synchronous wheel 6152 is fixedly connected with the synchronous shaft body 614, thereby driving the synchronous shaft body 614 to rotate. The locking wheel 613 is fixedly connected with the synchronous shaft body 614, thereby driving the locking wheel 613 to rotate, realizing the locking or releasing of the locking device 6. The chain, the rotating rod and the rotating wheel are made of high-strength, wear-resistant materials, which can ensure the stability and durability of the transmission, thereby prolonging the service life of the locking device 6.

[0152] The second driving part 615 drives the two synchronous shaft bodies 614 to rotate synchronously, simplifying the operation difficulty when locking. Whether using the pusher sliding, rotating rod rotating and other ways, the user can easily and quickly realize the locking and releasing function, effectively improving the locking efficiency. This design reduces the complexity and time cost of manual operation, improves the use convenience of the printer.
