Description

Technical Field

[0001] This application relates to the field of printer technology, and more specifically, to a tabletop platform and a direct-injection printer. Background Technology

[0002] "Direct inkjet printer" is short for "digital direct inkjet printer" or "direct inkjet printing equipment." It is an industrial-grade digital inkjet device widely used for printing patterns on the surfaces of various materials such as textiles, advertising, packaging, ceramics, glass, and metals. Its core feature is that it can directly spray ink onto the surface of the substrate, without the need for intermediate media such as screens or transfer paper as in traditional printing.

[0003] When printing with an inkjet printer, the printing medium is usually supported by a platen. The platen specifications vary and can be replaced as needed. However, it is required that the flatness of the platen can be easily adjusted after replacement to ensure printing accuracy.

[0004] In related technologies, external equipment is usually required, and the platform needs to be adjusted by professional technicians through a complex adjustment mechanism. This results in a complex structure, high cost, and is not conducive to operation by end users. Utility Model Content

[0005] In order to at least address some of the deficiencies mentioned in the related technologies, this application provides a platform and a direct injection machine.

[0006] To achieve the above objectives, a printing platform is provided for direct-to-garment printers. The printing platform includes a base, an adjusting member, and a printing plate. The adjusting member is mounted on the base and is capable of sliding vertically on the base. The printing plate is mounted on the adjusting member, and the adjusting member has multiple limiting grooves on its side facing the printing plate. Elastic members are disposed within the limiting grooves and can abut against the printing plate. Through holes are formed on the printing plate corresponding to the limiting grooves, and limiting members are inserted into the through holes. The limiting members pass through the elastic members and are inserted into the limiting grooves, and are relatively fixed to the limiting grooves.

[0007] Furthermore, the plurality of limiting grooves are provided in a one-to-one correspondence with the plurality of through holes; the plurality of through holes are distributed at the edge of the platform.

[0008] Furthermore, two adjusting members are symmetrically arranged on two opposite sides of the base. The two adjusting members are respectively installed on two opposite edges of the platform.

[0009] Furthermore, the limiting groove includes an elastic section and a threaded section, with the elastic element installed within the elastic section. The limiting element is provided with an external thread, allowing it to pass through the elastic element and be threadedly connected to the threaded section.

[0010] Furthermore, the base has multiple threaded holes, and bolts are installed in the threaded holes. The adjusting member has a vertical groove, and the bolt passes through the vertical groove and connects to the threaded hole.

[0011] Furthermore, the adjusting member has a horizontally arranged mounting surface, and the platform is mounted on the mounting surface. The adjusting member also has an adjusting surface, which is adjacent to the mounting surface and perpendicular to the mounting surface, and the straight groove is formed on the adjusting surface.

[0012] Furthermore, multiple straight grooves are distributed on the adjustment surface, and the straight grooves are located on the adjustment surface near the limiting groove.

[0013] Furthermore, the base includes a mounting end and a supporting end, the supporting end being used to support the mounting end, and the mounting end being arranged parallel to the supporting end. The adjusting member is mounted on the mounting end, and the length of the adjusting member is the same as the length of the mounting end.

[0014] Furthermore, the length of the support end is L1, and the length of the mounting end is L2, satisfying: L1 / L2≥1 / 2.

[0015] This application provides a direct injection printer, including a printing device and a table platform as described in any of the above embodiments, the table platform being used to support the printing medium.

[0016] With the above technical solution, when using the platform of this application, the adjusting component is first adjusted so that it slides vertically on the base, causing the platform to slide synchronously and bringing it to a roughly horizontal position. Then, the limiting component is adjusted to control the depth of its insertion into the limiting groove. This means the limiting component compresses the elastic component through the platform, changing the distance between the platform and the adjusting component, thus achieving platform leveling. Multiple limiting components are adjusted repeatedly until the platform is horizontal.

[0017] The platform of this application can be leveled by directly adjusting the adjusting parts and limiting parts without the need for other complicated debugging equipment. It has a simple structure, is easy to operate, has low cost, and is convenient for end customers to adjust the platform themselves.

[0018] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0025] This embodiment provides a platform to solve the problems in related technologies, such as the need for other complex adjustment mechanisms to level the platform 300, which makes operation difficult, highly specialized, and not easy to operate.

[0026] Please see Figures 1 to 4 This embodiment provides a printing platform for a direct-to-garment printer. The printing platform includes a base 100, an adjusting member 200, and a printing plate 300. The adjusting member 200 is mounted on the base 100 and can slide vertically on the base 100. The printing plate 300 is mounted on the adjusting member 200. Multiple limiting grooves 230 are provided on the side of the adjusting member 200 facing the printing plate 300. Elastic members 232 are provided within the limiting grooves 230 and can abut against the printing plate 300. Through holes 310 are provided on the printing plate 300 corresponding to the positions of the limiting grooves 230. Limiting members 231 are inserted into the through holes 310, passing through the elastic members 232 and inserted into the limiting grooves 230. The limiting members 231 can be fixed relative to the limiting grooves 230.

[0027] Specifically, when using the platform of this embodiment, the adjusting member 200 is first adjusted so that it slides vertically on the base 100. The platform 300 is installed on the adjusting member 200. The adjusting member 200 moves vertically, that is, the platform 300 moves vertically, so that the platform 300 is roughly horizontal. Then the adjusting member 200 is fixed relative to the base 100.

[0028] The limiting member 231 passes through the through hole 310 of the platform 300 and is inserted into the limiting groove 230 on the adjusting member 200. An elastic member 232 is provided within the limiting groove 230, with one end of the elastic member 232 abutting against the platform 300. Thus, by controlling the depth of the limiting member 231 inserted into the limiting groove 230, the platform 300 can be controlled to compress or release the elastic member 232, changing the relative distance between the platform 300 and the adjusting member 200. By adjusting multiple limiting members 231 sequentially, the platform 300 can be brought into a horizontal position.

[0029] The platform in this embodiment requires no other complex adjustment mechanisms or professional technicians for leveling. Its overall structure is simple, easy to operate, and low-cost. End users can directly adjust the platform 300 themselves, making it highly practical.

[0030] It is understandable that, in this embodiment, leveling the platform 300 can be achieved by using other simple equipment such as a level. The level can be placed directly on the platform 300, and then the platform 300 can be adjusted.

[0031] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, multiple limiting grooves 230 are correspondingly arranged with multiple through holes 310; the multiple through holes 310 are distributed along the edge of the platform 300. By distributing multiple limiting structures along the edge of the platform 300, multi-point support for the platform 300 is achieved. This allows for a more even distribution of the load borne by the platform 300, avoiding deformation or warping caused by localized stress concentration, thereby improving the overall structural stability of the platform 300 and its ability to maintain its level after adjustment.

[0032] The edges are a key area for determining whether a plane is level. Setting multiple adjustment points at the edges allows for more accurate detection and correction of height differences at the four corners and sides of the printing platen 300, achieving higher precision plane adjustment and ensuring that the entire surface of the printing platen 300 is in an ideal level state to meet the requirements of high-precision printing.

[0033] Each limit point can be adjusted independently, allowing users to adjust the height of each corner of the platform 300 individually. For example, if a corner is too low, it can be raised by reducing the compression of the elastic element 232 at that point, and vice versa. Independent adjustment makes the leveling process more flexible and intuitive.

[0034] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, two adjusting members 200 are symmetrically arranged on two opposite sides of the base 100. The two adjusting members 200 are respectively installed on two opposite edges of the platform 300. Compared to single-point or single-sided support, the symmetrically arranged adjusting members 200 on both sides provide end support for the platform 300. This support method can effectively resist bending deformation of the platform 300 under its own weight, printhead scanning impact, or material placement, significantly improving overall rigidity and load-bearing capacity. Single-sided support is prone to torsional deformation or lateral tilting of the platform 300 due to uneven force distribution. The symmetrical arrangement on both sides balances the force on both sides, effectively suppressing the torsional tendency of the platform 300 and ensuring its stable posture during leveling and use.

[0035] The two adjusting components 200 can be simultaneously adjusted vertically, enabling rapid and consistent adjustment of the overall height of the printing platen 300. This is equivalent to completing the "coarse adjustment" step, bringing the printing platen 300 roughly level and to a suitable printing height. Because of the symmetrical design, users can ensure that the adjusting components 200 on both sides are at the same height during adjustment, avoiding initial deviations where one side is higher than the other, thus laying a good foundation for subsequent fine leveling using the limiting component 231.

[0036] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, the limiting groove 230 includes an elastic section and a threaded section, with the elastic element 232 installed within the elastic section. The limiting element 231 has external threads, allowing it to pass through the elastic element 232 and be threaded into the threaded section. When the limiting element 231 is screwed into the threaded section, it compresses the elastic element 232, applying controllable elastic pressure to the platform 300. By rotating the depth of the limiting element 231, the compression amount of the elastic element 232 can be precisely controlled, thereby adjusting the clamping force on the platform 300. This ensures reliable fixation of the platform 300 while avoiding stress concentration or deformation of the platform 300 due to rigid locking, making it particularly suitable for materials with significant thermal expansion and contraction.

[0037] Threaded connections are characterized by good self-locking properties and high adjustment precision. The axial movement of the limiting element 231 with each rotation is determined by the thread pitch, enabling high-precision fine-tuning. When using a level, users can slowly and continuously fine-tune a specific limiting point to gradually eliminate tilt errors and achieve a high-precision level.

[0038] Threaded connections inherently possess high connection strength and shear resistance. The elastic element 232 provides a preload, keeping the entire connection in a pre-tightened state, effectively reducing loosening, resonance, or gap vibration caused by the high-speed reciprocating motion of the printhead. Even during long-term operation, the connection remains stable, preventing printing misalignment due to loosening.

[0039] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, the base 100 has multiple threaded holes, and bolts are installed in these holes. The adjusting component 200 has a vertical groove 221, through which the bolt passes and connects to the threaded hole. The groove 221 allows the bolt to slide vertically within it, thus enabling the adjusting component 200 to move up and down within a certain range. Users can manually adjust the height of the adjusting component 200 or use tools by loosening the bolts; after adjusting to the appropriate position, retightening the bolts will fix the adjusting component 200 to the base 100. This achieves stepless continuous adjustment of the adjusting component 200 in the vertical direction, eliminating the need for increments or positioning holes, making adjustment more flexible and adaptable to different thicknesses of the printing plate 300 or printing height requirements.

[0040] The platform 300 is initially adjusted using the straight groove 221 and bolt structure. Users can quickly adjust the height of the adjusting component 200 without disassembling any parts, laying the foundation for subsequent fine-tuning using the limiting component 231. After adjustment, the bolts are tightened, forming a rigid connection between the adjusting component 200 and the base 100, eliminating the gap between the straight groove 221 and the bolts, and ensuring structural stability. Multiple bolts distributed at different positions on the adjusting component 200 effectively prevent displacement, shaking, or torsion during use, improving overall rigidity and seismic resistance.

[0041] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, the adjusting component 200 has a horizontally arranged mounting surface 210, on which the platform 300 is mounted. The adjusting component 200 also has an adjusting surface 220, which is adjacent to and perpendicular to the mounting surface 210. A straight groove 221 is formed on the adjusting surface 220. The mounting surface 210 is specifically used to support and fix the platform 300, ensuring stable installation, a large contact area, and uniform force distribution. The adjusting surface 220 is specifically used to house the straight groove 221 and connecting bolts, undertaking both adjustment and locking functions. This spatial separation of the "supporting function" and the "adjusting function" avoids mutual interference. For example, tightening or loosening the adjusting bolts will not directly affect the mounting plane of the platform 300, improving the stability and accuracy of the leveling process.

[0042] The straight groove 221 and the bolt are located on the vertical adjustment surface 220, which keeps the connection point away from the mounting surface 210, resulting in a greater structural height. This is equivalent to increasing the moment of inertia of the adjustment component 200, significantly improving its bending and torsional stiffness, and preventing the adjustment component 200 from deforming or tilting under stress. Even after frequent adjustments or long-term use, the structure remains stable, avoiding leveling failure due to deformation of the adjustment surface 220.

[0043] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, multiple straight grooves 221 are distributed on the adjustment surface 220, and the straight grooves 221 are located on the adjustment surface 220 near the limiting groove 230. The multiple straight grooves 221 are distributed, meaning that the adjusting component 200 is connected to the base 100 by multiple bolts, forming a multi-point fixed support. This effectively prevents the adjusting component 200 from twisting, tilting, or shifting during height adjustment or locking, especially maintaining structural stability when tightening or loosening bolts on one side. It avoids the "lever effect" or "warping deformation" caused by single-point or two-point connections, ensuring that the adjusting component 200 always provides reliable support to the platform 300.

[0044] Multiple straight grooves 221, combined with multiple bolts for fastening, make the connection between the adjusting component 200 and the base 100 more secure, significantly improving the shear stiffness and vibration resistance of the connection. During high-speed printing in the direct-to-garment printer, it can effectively suppress the transmission of micro-vibrations caused by the reciprocating motion of the printhead to the table 300, reducing the risk of printing ghosting or misalignment.

[0045] The limiting groove 230 is located on the adjusting member 200, where the elastic member 232 and the limiting member 231 are installed. It serves as the point of application for local leveling of the platform 300. By placing the straight groove 221 close to the limiting groove 230, the leveling point of the platform 300 and the support fixing point of the adjusting member 200 are spatially close, shortening the load transmission lever arm. This reduces the bending moment and deflection deformation generated on the adjusting member 200 when the platform 300 is under stress, improving the efficiency of leveling accuracy transmission. In other words, fine adjustments made by the operator at the limiting groove 230 will not be amplified or distorted by distant support points, avoiding the leverage effect caused by "far-end support, near-end leveling," and ensuring that the leveling result is accurately reflected on the entire plane of the platform 300.

[0046] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, the base 100 includes a mounting end 110 and a supporting end 120. The supporting end 120 supports the mounting end 110, and the mounting end 110 and the supporting end 120 are arranged parallel to each other. An adjusting member 200 is installed on the mounting end 110, and the length of the adjusting member 200 is the same as the length of the mounting end 110. The supporting end 120 and the mounting end 110 are arranged parallel to each other, forming a "frame-like" or "double-layered" structure, connected in the middle by connecting ribs, columns, or side walls. This design significantly improves the bending and torsional stiffness of the base 100, preventing instability of the printing plate 300 or a decrease in printing accuracy due to deformation of the base 100. It is especially suitable for large-size direct-to-garment printers, effectively resisting vibrations and external interference during equipment operation, ensuring long-term accuracy stability.

[0047] The mounting end 110 supports the adjusting component 200 and the platform 300, serving as the primary "working surface." The support end 120 acts as the base surface, evenly distributing the load to the ground or frame. The two are parallel and connected by a support structure, ensuring that pressure and impact from the platform 300 are transmitted to the bottom support surface via the shortest and most direct path, avoiding eccentric forces or cantilever effects. This extends the lifespan of the base 100 and prevents localized deformation from affecting the leveling effect.

[0048] The adjusting member 200 is arranged along the entire length of the mounting end 110, meaning its supporting function covers the entire mounting area. If two symmetrically arranged adjusting members 200 are used, continuous or near-continuous support is formed along the entire width. This prevents the center of the platform 300 from sagging, improves the overall flatness retention of the platform 300, makes the force on the platform 300 more even, and avoids common problems such as high edges and low center.

[0049] In one embodiment, exemplarily, such as Figures 1 to 4 As shown, the length of the support end 120 is L1, and the length of the mounting end 110 is L2, satisfying: L1 / L2≥1 / 2. The mounting end 110 supports the adjusting component 200 and the platform 300, serving as the upper working platform of the equipment, and its length is typically relatively long. If the support end 120 is too short, the base 100 will have insufficient support area, resulting in a top-heavy structure that is prone to lateral overturning or torsional instability during equipment handling, operational vibration, or eccentric loading. In this embodiment, the support end 120 covers at least half the length of the mounting end 110, providing sufficient anti-overturning lever arm and support range, significantly improving the overall structural stability.
