Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a lifting device for printing equipment and a printing equipment. Background Technology

[0002] During the operation of fabric printing equipment such as direct-to-garment printers and digital printers, the thickness of different fabric materials varies significantly, and the distance between the print head and the fabric surface must be strictly controlled within a specific process window; otherwise, quality problems such as ink droplet splatter, blurred patterns, or print head scratching may occur. To adapt to the printing needs of various thicknesses, existing technologies generally adopt a mechanical table support structure, that is, the overall height of the printing table is adjusted by changing the support base of different heights.

[0003] Replacing the existing support base requires multiple people working together. It involves disassembling multiple sets of fixing bolts, removing the original base, installing the new base, and readjusting it. The entire process is time-consuming and carries risks such as stripped bolts and the base potentially damaging the print head. Furthermore, accuracy calibration is difficult. After each base replacement, the platen must undergo three-dimensional accuracy calibration, including levelness, flatness, and height repeatability. Traditional calibration relies on manual operation, requiring repeated measurements and corrections using various tools. This not only requires skilled technicians but is also susceptible to environmental factors, often necessitating multiple adjustments to achieve the required accuracy, resulting in lengthy calibration times. Additionally, in a "small batch, multi-variety" production model, the equipment requires frequent platen support base replacements, leading to significant downtime and direct production losses. Simultaneously, frequent mechanical disassembly accelerates component wear and increases equipment maintenance costs. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides a lifting device for printing equipment and a printing equipment.

[0005] This utility model provides the following technical solution: A lifting device for a printing equipment includes a base, a translation component, and a lifting component.

[0006] The base has a first slide rail along the horizontal direction; the translation component is mounted on the base and includes a drive motor, a transmission shaft, a slider, and a transmission seat. The drive motor is fixedly mounted on the base, and the drive motor shaft is drivenly connected to the transmission shaft. The transmission shaft has a threaded section, and the slider is threaded onto the threaded section. The slider is fixedly connected to the transmission seat, and the transmission seat has a first mating groove and a transition part corresponding to the first slide rail. The first slide rail passes through the first mating groove. The lifting component is mounted on the base and is drivenly engaged with the transition part of the transmission seat. The lifting component is assembled and connected to the printing platen of the printing equipment. The drive motor shaft rotates, thereby driving the transmission shaft, which in turn drives the slider and the transmission seat to move along the first slide rail, ultimately driving the lifting component to lift the printing platen.

[0007] As a further improvement to the above technical solution, the lifting assembly includes a support base corresponding to the transmission base, the support base having a mating part corresponding to the adapter, the adapter being connected to the mating part in a transmission manner; the support base also has a second slide rail, the base having a second mating groove corresponding to the second slide rail, the second mating groove being arranged vertically, the second slide rail passing through the second mating groove; the upper top surface of the support base is assembled and connected to the printing platen of the printing equipment.

[0008] As a further improvement to the above technical solution, two transmission seats are provided symmetrically relative to the slider.

[0009] As a further improvement to the above technical solution, at least two second slide rails are provided in the horizontal direction.

[0010] As a further improvement to the above technical solution, the end face of the support base near the transmission base is provided with a mating post, which is used to form a mating part. The end face of the transmission base near the support base is provided with a guide groove, which is used to form the transition part. The mating post passes through the guide groove. The transmission base moves along the guiding direction of the first slide rail, which can drive the mating post to move in the guide groove, thereby driving the support base to move along the guiding direction of the second mating groove.

[0011] As a further improvement to the above technical solution, the guide groove is a straight groove that is inclined relative to the horizontal plane.

[0012] As a further improvement to the above technical solution, the angle between the guide groove and the horizontal plane is α, and the value range of α is: 40°≤α≤60°.

[0013] As a further improvement to the above technical solution, at least two guide grooves are provided in parallel along the horizontal direction.

[0014] As a further improvement to the above technical solution, a manual knob is provided at the end of the transmission shaft opposite to the drive motor.

[0015] This utility model also provides a printing device, including the lifting device for printing devices as described above.

[0016] Compared with related technologies, the beneficial effects of this utility model are: The lifting device for printing equipment provided by this utility model allows the operator to start the drive motor and drive the connected transmission shaft to rotate when the height of the printing table needs to be adjusted according to different printing requirements during the actual use of the printing equipment.

[0017] Driven by the drive motor, the drive shaft begins to rotate at a constant speed. At this time, the slider, which is threaded onto the drive shaft, will produce corresponding movement. Because the slider and the drive shaft are connected by a thread, when the drive shaft rotates, the slider will move linearly along the axial direction of the drive shaft. This threaded connection design is not only simple in structure, but also ensures the smoothness and accuracy of the slider's movement.

[0018] As the slider moves, it drives the connected transmission seat to move along the first slide rail. The first slide rail guides the movement of the transmission seat, ensuring that the transmission seat can only move in a straight line along a predetermined path, avoiding deviation and wobbling during the movement.

[0019] During the movement of the transmission base, it connects with the lifting assembly via the adapter, thereby driving the lifting assembly to move up and down. Driven by the transmission base, the lifting assembly moves up and down in a predetermined direction and amplitude, and its movement is stable and controllable.

[0020] Ultimately, the lifting assembly will cause the print platen connected to it to adjust its height. As a key component of the printing equipment, the accuracy of the print platen's height directly affects the print quality. The lifting device provided by this invention enables precise adjustment of the print platen's height, meeting the needs of different printing scenarios.

[0021] The entire operation described above offers numerous advantages. First, it facilitates automatic height adjustment of the printing platen, eliminating the need for manual operation and significantly saving labor and time costs while improving adjustment efficiency. Operators can easily adjust the printing platen height simply by controlling the start and stop of the drive motor, making operation simple and convenient. Second, the threaded engagement between the slider and the drive shaft ensures precise height adjustment of the printing platen. This threaded engagement has a self-locking function, guaranteeing the stability of the slider's position on the drive shaft and ensuring accurate height adjustment of the printing platen. Finally, by converting the driving force of the drive motor that moves the slider horizontally into the driving force that adjusts the vertical height of the printing platen, this transmission design ensures stability during height adjustment. Throughout the entire height adjustment process, the printing platen will not wobble or vibrate, maintaining a stable state and guaranteeing consistent and stable print quality.

[0031] Combination Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a lifting device for a printing equipment, including a base 100, a translation component 200, and a lifting component 300.

[0032] The base 100 is provided with a first slide rail 110 along the horizontal direction; the translation component 200 is mounted on the base 100, and the translation component 200 includes a drive motor 210, a transmission shaft 220, a slider 230, and a transmission seat 240. The drive motor 210 is fixedly mounted on the base 100, and the rotating shaft of the drive motor 210 is connected to the transmission shaft 220 through a coupling or other transmission structure. The transmission shaft 220 is provided with a threaded section 221, and the slider 230 is sleeved on the threaded section 221 by a threaded engagement. The slider 230 is fixedly connected to the transmission seat 240. The transmission base 240 is provided with a first mating groove 241 corresponding to the first slide rail 110 and a connecting part, and the first slide rail 110 passes through the first mating groove 241; the lifting assembly 300 is mounted on the base 100 and is in transmission cooperation with the connecting part of the transmission base 240, and the lifting assembly 300 is assembled and connected to the printing plate of the printing equipment; the shaft of the drive motor 210 rotates, thereby driving the transmission shaft 220, which in turn drives the slider 230 and the transmission base 240 to move along the first slide rail 110, and finally drives the lifting assembly 300 to lift the printing plate.

[0033] The lifting device for the printing equipment provided in this embodiment allows the operator to start the drive motor 210 and drive the transmission shaft 220 connected to it to rotate when the height of the printing table needs to be adjusted according to different printing requirements during the actual use of the printing equipment.

[0034] Driven by the drive motor 210, the drive shaft 220 begins to rotate at a constant speed. At this time, the slider 230, which is threaded onto the drive shaft 220, will produce corresponding movement. Because the slider 230 and the drive shaft 220 are connected by a thread, when the drive shaft 220 rotates, the slider 230 will move linearly along the axial direction of the drive shaft 220. This threaded connection design is not only simple in structure, but also ensures the smoothness and accuracy of the slider 230's movement.

[0035] As the slider 230 moves, it drives the connected transmission seat 240 to move along the first slide rail 110. The first slide rail 110 provides guidance for the movement of the transmission seat 240, ensuring that the transmission seat 240 can only move in a straight line along a predetermined path, avoiding deviation and wobbling during the movement.

[0036] During the movement of the transmission base 240, it connects with the lifting assembly 300 via the adapter, thereby driving the lifting assembly 300 to move up and down. Driven by the transmission base 240, the lifting assembly 300 moves up and down in a predetermined direction and amplitude, and its movement is stable and controllable.

[0037] Ultimately, the lifting assembly 300 will drive the printing platen connected to it to adjust its height. As a key component of the printing equipment, the accuracy of the printing platen's height directly affects print quality. The lifting device provided by this invention enables precise adjustment of the printing platen's height, meeting the needs of different printing scenarios.

[0038] The entire operation described above offers numerous advantages. First, it facilitates automatic height adjustment of the printing platen, eliminating the need for manual operation and significantly saving labor and time costs while improving adjustment efficiency. Operators can easily adjust the printing platen height simply by controlling the start and stop of the drive motor 210, making operation simple and convenient. Second, the threaded engagement between the slider 230 and the drive shaft 220 ensures precise height adjustment of the printing platen. This threaded engagement has a self-locking function, guaranteeing the stability of the slider 230's position on the drive shaft 220, thus ensuring accurate height adjustment of the printing platen. Finally, by converting the driving force of the drive motor 210 that moves the slider 230 horizontally into the driving force that adjusts the vertical height of the printing platen, this transmission design ensures stability during height adjustment. Throughout the entire height adjustment process, the printing platen will not wobble or vibrate, maintaining a stable state and ensuring consistent and stable print quality.

[0039] In some specific embodiments, the machine body is also provided with a plurality of bearing seats 222 for supporting the drive shaft 220, and the drive shaft 220 passes through each of the bearing seats 222 in sequence to ensure the smooth rotation of the drive shaft 220.

[0040] In some specific embodiments, the lifting assembly 300 includes a support base 310 corresponding to the transmission base 240. The support base 310 has a mating part corresponding to the adapter, and the adapter is connected to the mating part in a transmission manner. The support base 310 also has a second slide rail 320, and the base 100 has a second mating groove 120 corresponding to the second slide rail 320. The second mating groove 120 is arranged vertically, and the second slide rail 320 passes through the second mating groove 120, so that the support base 310 can only move in a straight line in the vertical direction, effectively preventing the support base 310 from shifting or swaying horizontally during movement, thereby improving the movement accuracy and stability of the entire lifting assembly 300. The upper top surface of the support base 310 is assembled and connected to the printing platen of the printing device. This assembly and connection method adopts a reliable mechanical connection structure, such as using bolts, screws, or other fasteners to firmly fix the printing platen to the upper top surface of the support base 310. Through this connection, when the support base 310 moves up and down under the drive of the lifting component 300, the printing platen can be adjusted in height synchronously and stably, ensuring that the printing platen remains horizontal during the adjustment process, thus meeting the precise height requirements of the printing equipment for different printing tasks.

[0041] In some specific embodiments, two transmission seats 240 are symmetrically provided relative to the slider 230, which facilitates the improvement of the transmission reliability between the transmission seats 240 and the support seats 310; that is, two corresponding support seats 310 are also symmetrically provided, which facilitates the increase of the connection positions between the support seats 310 and the printing platen, thereby improving the stability and reliability of the support seats 310 in providing support for the printing platen.

[0042] In some specific embodiments, at least two second slide rails 320 are provided in the horizontal direction to improve the reliability of the second mating groove 120 in guiding the support 310 to move in the vertical direction.

[0043] In some specific embodiments, the support base 310 has a mating post 311 on its end face near the transmission base 240, which forms a mating part. The transmission base 240 has a guide groove 242 on its end face near the support base 310, which forms the transition part. The mating post 311 passes through the guide groove 242. The transmission base 240 moves along the guide direction of the first slide rail 110, which can drive the mating post 311 to move within the guide groove 242. While the mating post 311 moves within the guide groove 242, it can drive the support base 310 to move along the guide direction of the second mating groove 120, thereby driving the printing platen to move vertically up and down, ensuring the smoothness of the process of driving the printing platen to move up and down.

[0044] In some specific embodiments, the guide groove 242 is a straight groove inclined relative to the horizontal plane. From the perspective of motion principle, when the transmission seat 240 moves horizontally under the action of the driving device, since the guide groove 242 is inclined, the mating post 311 passing through the guide groove 242 will be subjected to a component force along the direction of the guide groove 242. This component force will cause the mating post 311 to drive the connected support seat 310 to move. The straight groove design of the guide groove 242 ensures that the movement trajectory of the mating post 311 in the guide groove 242 is linear and stable during the horizontal movement of the transmission seat 240.

[0045] The significance of this design lies in its ability to ensure a linear relationship between the horizontal movement of the transmission seat 240 and the vertical movement of the support seat 310. In other words, there is a precise and predictable proportional relationship between the horizontal distance the transmission seat 240 moves and the vertical distance the support seat 310 moves. For example, when the transmission seat 240 moves a certain distance horizontally, the support seat 310 will move a corresponding distance vertically in a fixed proportion. This linear relationship makes the entire adjustment process more intuitive and controllable.

[0046] In practice, this linear relationship greatly reduces the difficulty of adjustment. Users do not need to rely on complex experience or make multiple attempts to adjust the height of the printing platen; they only need to control the horizontal movement distance of the drive seat 240 according to the required vertical movement distance in a linear proportion.

[0047] This design also facilitates precise adjustment of the print platen by the user. Because the movement process has a clear linear relationship, as long as the drive precision of the transmission device is guaranteed, the horizontal movement distance of the transmission seat 240 can be precisely controlled, thereby precisely controlling the vertical movement distance of the support seat 310, ultimately achieving precise adjustment of the print platen height. Whether in small-scale fine-tuning or large-scale adjustments, the accuracy of the adjustment is guaranteed, meeting the stringent requirements of different printing scenarios for print platen height.

[0048] In some specific embodiments, the angle between the guide groove 242 and the horizontal plane is α, and the value of α ranges from 40° to 60°. This specific angle range has several important functions. First, it ensures that the printing platen can achieve a suitable lifting speed during the horizontal movement of the transmission seat 240. When the transmission seat 240 moves horizontally under the action of the driving force, due to the inclined setting of the guide groove 242, the mating column 311 passing through the guide groove 242 will be subjected to a component force along the direction of the guide groove 242, thereby driving the support seat 310 and the printing platen connected to the support seat 310 to move up and down. Within this angle range, a reasonable proportional relationship can be formed between the horizontal movement distance of the transmission seat 240 and the lifting distance of the printing platen, thereby ensuring that the printing platen lifts and lowers at a speed that is neither too fast nor too slow, meeting the speed adjustment requirements in actual printing operations.

[0049] Secondly, this angle range helps ensure the smoothness of the mating column 311 during its movement within the guide groove 242. When the transmission seat 240 moves horizontally, the mating column 311 moves relative to the guide groove 242. If the angle of the guide groove 242 is not set appropriately, the mating column 311 is prone to wobbling, jamming, and other unstable phenomena during movement. However, when α is in the range of 40° to 60°, the guide groove 242 provides a suitable guiding effect for the mating column 311, allowing it to move smoothly and stably within the guide groove 242. This reduces vibration and impact caused by unstable movement, thereby ensuring the stability and reliability of the entire lifting device.

[0050] From another perspective, limiting the value of α to this range also avoids two extreme cases. On the one hand, if the guide groove 242 is too tilted, i.e., α is less than 40°, then the horizontal movement of the transmission seat 240 will drive the print platen to move too slowly in the vertical direction. In actual operation, this will cause the user to spend a lot of time adjusting the height of the print platen, greatly reducing the adjustment efficiency. Especially in printing tasks that require frequent height adjustments, this excessively slow adjustment speed will seriously affect the overall work progress.

[0051] On the other hand, if the guide groove 242 is too vertically oriented, i.e., α is greater than 60°, the mating column 311 will move too quickly within the guide groove 242 as the transmission seat 240 moves horizontally. This rapid movement of the mating column 311 will also cause the printing platen to rise and fall too quickly, making it difficult for the user to precisely control the stopping position of the printing platen, thus affecting adjustment accuracy. Furthermore, excessively fast rising and falling speeds may also generate significant inertial forces in the entire lifting device, leading to instability during operation and potentially damaging other components of the printing equipment. Therefore, setting the value of α to 40°≤α≤60° is the optimal solution after comprehensively considering factors such as adjustment speed, adjustment accuracy, and device stability.

[0052] In some specific embodiments, at least two guide grooves 242 are provided in parallel along the horizontal direction to ensure the reliability of the transmission engagement between the transmission seat 240 and the support seat 310.

[0053] In some specific embodiments, the end of the drive shaft 220 away from the drive motor 210 is provided with a manual knob 223. The operator can rotate the drive shaft 220 by holding and turning the manual knob 223 to meet the needs of manual adjustment of the printing equipment.

It includes the lifting device for printing devices in the above embodiments. The lifting device for printing devices is installed between the body of the printing device and the printing table.
