[0003] To protect the printhead, most existing printers have a bumper at the bottom of the printhead to prevent direct collisions between the printing material and the printhead caused by paper warping, uneven media, or platform abnormalities. However, traditional bumpers have a single function and their design does not take into account the needs of active thermal management, thus becoming disconnected from print quality assurance systems and creating a functional shortcoming. Summary of the Invention
[0004] This application discloses an anti-collision structure, a printhead, and a printer to solve the technical problem that anti-collision plates in related technologies do not meet the requirements for active thermal management.

[0006] In some designs, there are multiple mounting sections, with a first placement slot arranged around the multiple mounting sections.
[0007] In some solutions, the first placement slot includes a first placement part and a second placement part. The first placement part is arranged around a plurality of mounting parts, and both ends of the first placement part are respectively connected to the second placement part. The width of the second placement part is greater than the width of the first placement part. The first placement part is used to place the heating wire, and the second placement part is used to place the wires at both ends of the heating wire.
[0008] In some designs, the anti-collision assembly includes a fixed plate and an anti-collision plate, with the anti-collision plate being detachably mounted on the bottom of the fixed plate; The mounting section and the first placement slot are located on the fixing plate, and the spray hole is located on the anti-collision plate.
[0009] In some designs, one of the fixing plate and the anti-collision plate has multiple protrusions, and the other has multiple through holes corresponding to the protrusions; When installing the fixing plate and the anti-collision plate, the protrusion is located in the through hole, and one end of the bolt passes through the through hole and is connected to the protrusion.
[0010] In some designs, the anti-collision assembly also includes a second placement slot for holding a temperature probe. And / or, the sidewall of the anti-collision component is provided with a third placement slot for placing a magnet; And / or, the anti-collision assembly is provided with a plurality of first connection holes, and the anti-collision assembly is connected to the print head of the printer through the plurality of first connection holes; And / or, the two ends of the sidewall of the anti-collision component are respectively provided with second connection holes, and the anti-collision component is connected to the print head of the printer through the second connection holes.
[0011] Secondly, this application also discloses a printhead used in a printer, which is installed in the anti-collision structure of the first aspect, and the printhead is fixed to the mounting part.

[0015] The technical solution adopted in this utility model can achieve the following beneficial effects: The anti-collision structure of this application, by fixing the printhead with the mounting part and providing a channel for ink through the bottom ejection hole, actively generates heat through the built-in heating wire. Utilizing the thermal conductivity of the anti-collision component itself, the heat is continuously and stably transferred to the printhead above it (keeping the ink warm) and the printing medium below (preheating), thereby creating a localized, controlled temperature field near the printhead. This transforms the originally passive, cold anti-collision plate into an active, integrated thermal management platform, stabilizing ink viscosity and ejection performance from the source, effectively preventing printing defects caused by excessively low temperatures, and avoiding the high energy consumption and slow response problems associated with relying on external heating solutions. It achieves highly efficient synergy between protective and thermal management functions. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

[0021] During their research on printers, the inventors discovered that traditional bumpers were always designed as passive, single-function protective components, their core function being merely to withstand physical impacts. This design philosophy led to a complete disconnect between the bumper and the crucial thermal management aspect of print quality assurance systems. During printing, the viscosity, surface tension, and adhesion and drying speed of ink on the medium are highly dependent on a stable and suitable temperature environment. However, traditional bumpers are cold and cannot preheat the printing medium passing beneath them, nor can they keep the ink about to be ejected from the printhead warm. When the ambient temperature is low, the ink viscosity increases, leading to poor ejection, ink interruptions, misaligned spraying, and even nozzle blockage. In severe cases, this can result in quality defects such as stripes and missing colors in the printed image. In such situations, the entire printing system must rely on an additional, independent heating module to raise the temperature of the entire print chamber, resulting in high energy consumption and slow response. Therefore, traditional bumpers are functionally limited, their design failing to consider proactive thermal management needs, thus creating a functional weakness that is disconnected from print quality assurance systems.
[0022] The following is in conjunction with the appendix Figures 1 to 5 The present application provides a detailed description of an anti-collision structure, a printhead 200, and a printer through specific embodiments and application scenarios.
[0023] Some embodiments of this application disclose an anti-collision structure applied to a printer, including an anti-collision component 100.
[0024] like Figure 1 and Figure 3 As shown, the anti-collision assembly 100 has a mounting part 111 for placing the nozzle 200. By fixing the nozzle 200, the mounting part 111 combines it with the anti-collision assembly 100 into a rigid, integral force-bearing unit. This disperses the impact energy that would otherwise be borne solely by the nozzle 200 to the entire anti-collision assembly 100, which has a higher structural strength, thereby achieving more direct and effective physical protection for the nozzle 200.
[0025] like Figure 1 and Figure 4 As shown, the bottom of the anti-collision component 100 has a through-hole 121 corresponding to the nozzle of the printhead 200. The through-hole 121 ensures that the anti-collision component 100 provides comprehensive physical protection for the printhead 200 while providing an unobstructed path for ink ejection, thus precisely balancing the protective function and the printing function.
[0026] like Figure 1 and Figure 3 As shown, the anti-collision component 100 has a first placement slot 112 for placing the heating wire. Integrating the heating wire into the first placement slot 112 transforms the anti-collision component 100 from a single physical protective component into a composite component with active heating function, achieving a compact spatial layout. Furthermore, through heat conduction by the anti-collision component 100, heat is transferred more directly and efficiently to the printhead 200 and the printing media flowing beneath it, significantly improving the response speed and energy efficiency of thermal management, fundamentally solving the problems of slow response and high energy consumption of independent external heating modules in traditional solutions.
[0027] like Figure 1 and Figure 3 As shown, there are multiple mounting portions 111, and first placement slots 112 are arranged around the multiple mounting portions 111. By arranging the first placement slots 112 around the multiple mounting portions 111, it is ensured that the heat generated by the heating wire can be synchronously and evenly conducted to all printheads 200, thereby forming a stable and balanced temperature field in the printhead 200 group area. This not only effectively eliminates the temperature gradient between multiple printheads 200, ensuring the consistency of ink viscosity and performance ejected by different printheads 200, but also improves the efficiency and quality of thermal management at the system level, avoiding print quality defects caused by uneven temperature of individual printheads 200.
[0028] like Figure 1 and Figure 3As shown, the first placement slot 112 includes a first placement portion 1121 and a second placement portion 1122. The first placement portion 1121 is arranged around multiple mounting portions 111, and both ends of the first placement portion 1121 are connected to the second placement portion 1122. The width of the second placement portion 1122 is greater than the width of the first placement portion 1121. The first placement portion 1121 is used to place the heating wire, and the second placement portion 1122 is used to place the wires at both ends of the heating wire. By functionally and morphologically separating the main heating area (first placement portion 1121) and the wire receiving area (second placement portion 1122), a unified approach of efficient thermal management and reliable electrical connection under a compact layout is achieved. The surrounding arrangement of the first placement portion 1121 ensures uniform heat radiation to the multiple nozzles 200, while the widened second placement portion 1122 provides ample and safe space for the wires, effectively avoiding wire bending, insulation wear, or installation stress caused by limited space. This enhances the safety and reliability of placing the heating wire while improving heating uniformity and temperature field stability.
[0029] In this embodiment, the two ends of the guide are also connected to a power source through the anti-collision assembly 100.
[0030] It should be noted that the width direction of the first placement part 1121 and the width direction of the second placement part 1122 are as follows: Figure 3 As shown in W.
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, the anti-collision assembly 100 includes a fixing plate 110 and an anti-collision plate 120, with the anti-collision plate 120 detachably mounted on the bottom of the fixing plate 110. The detachable connection between the fixing plate 110 and the anti-collision plate 120 enables the modularity of the anti-collision assembly 100. This allows for quick and cost-effective replacement of the anti-collision plate 120 in the event of wear or impact damage, without discarding the entire fixing plate 110, which integrates the heating wire and nozzle 200, thus greatly improving maintainability and cost-effectiveness.
[0032] In this embodiment, the mounting part 111 and the first placement groove 112 are disposed on the fixing plate 110, and the spray hole 121 is disposed on the anti-collision plate 120.
[0033] like Figure 3 and Figure 4As shown, one of the fixing plate 110 and the anti-collision plate 120 has multiple protrusions 122, and the other has multiple through holes 117 corresponding to the protrusions 122. When the fixing plate 110 and the anti-collision plate 120 are installed, the protrusions 122 are located in the through holes 117, and one end of the bolt passes through the through hole 117 and engages with the protrusion 122. Through the engagement of the protrusions 122 and the through holes 117, quick and precise pre-positioning can be achieved before the bolts are tightened, effectively preventing misalignment and slippage during installation, ensuring the uniqueness and correctness of the relative position between the anti-collision plate 120 and the fixing plate 110, thereby improving assembly efficiency and connection reliability. Furthermore, the bolt connection between the anti-collision plate 120 and the fixing plate 110 ensures a stable connection between the anti-collision plate 120 and the fixing plate 110 and facilitates disassembly.
[0034] Specifically, the protrusion 122 is provided with a threaded hole, and one end of the bolt passes through the through hole 117 and is connected to the threaded hole.
[0035] In some embodiments, a plurality of protrusions 122 are provided on the fixing plate 110, and a plurality of through holes 117 are provided on the anti-collision plate 120.
[0036] In some embodiments, a plurality of protrusions 122 are provided on the anti-collision plate 120, and a plurality of through holes 117 are provided on the fixing plate 110.
[0037] like Figure 1 and Figure 3 As shown, the anti-collision assembly 100 is also provided with a second placement slot 113, which is used to place a temperature probe. By providing a second placement slot 113 in the anti-collision assembly 100, the temperature probe can be installed, and the temperature probe can monitor the temperature of the anti-collision assembly 100 to ensure that the temperature of the anti-collision assembly 100 is within the ideal range.
[0038] In this embodiment, the second placement slot 113 is disposed on the fixing plate 110.
[0039] like Figure 1 and Figure 3 As shown, the side wall of the anti-collision component 100 is provided with a third placement groove 115, which is used to place a magnet. By placing a magnet in the third placement groove 115, when the cover of the spray truck is opened, the cover of the spray truck (which is magnetic) is attracted by the magnet placed in the third placement groove 115, so that the cover of the spray truck will not be accidentally closed, placed randomly, or lost during the maintenance of the spray truck, thereby ensuring the continuity, efficiency and safety of the maintenance process.
[0040] In this embodiment, the third placement slot 115 is disposed on the fixing plate 110.
[0041] like Figure 1 and Figure 3As shown, the anti-collision component 100 is provided with multiple first connection holes 114, through which the anti-collision component 100 is connected to the printhead of the printer. By providing multiple first connection holes 114, which are connected to the printhead of the printer by bolts, a stable connection is ensured between the anti-collision component 100 and the printhead, effectively improving the reliability of the connection between the anti-collision component 100 and the printhead under high-speed movement.
[0042] In this embodiment, the first connecting hole 114 is disposed on the fixing plate 110.
[0043] like Figure 2 and Figure 3 As shown, the anti-collision component 100 has second connection holes 116 at both ends of its sidewall. The anti-collision component 100 is connected to the printer's printhead through the second connection holes 116. The two second connection holes 116 are bolted to the printhead, applying constraints to both ends of the anti-collision component 100. This achieves a balanced force distribution, avoiding warping or resonance that may occur with single-point connections, and ensuring the flatness and dynamic stability of the anti-collision component 100 during installation.
[0044] In this embodiment, the second connecting hole 116 is disposed on the fixing plate 110.
[0045] Some embodiments of this application also disclose a printhead 200 used in a printer.
[0046] like Figure 1 As shown, the nozzle 200 is fixed to the mounting part 111. By fixing the nozzle 200, the mounting part 111 combines it with the anti-collision component 100 into a rigid whole force-bearing unit, dispersing the impact energy that was originally borne by the nozzle 200 alone to the entire anti-collision component 100, which has a higher structural strength, thereby achieving more direct and effective physical protection for the nozzle 200.
[0047] Specifically, the anti-collision component 100 has multiple mounting parts 111 to accommodate the simultaneous installation of multiple printheads 200 to meet printing requirements.
[0048] like Figure 1 and Figure 5 As shown, the bottom of the nozzle 200 abuts against the anti-collision component 100, and the side wall of the nozzle 200 is provided with a connecting part 210, which is connected to the mounting part 111 by bolts. By abutting the nozzle 200 against the anti-collision component 100 and bolting the side wall of the nozzle 200 to the mounting part 111, a two-way mechanical constraint is constructed. This ensures the precise positioning of the nozzle 200 in the vertical direction without wobbling, and eliminates horizontal displacement through lateral fastening. Thus, a stable and precise rigid connection is achieved between the nozzle 200 and the anti-collision component 100, effectively guaranteeing the spraying accuracy of the nozzle 200 during high-speed movement and the reliability of long-term operation.
[0049] In this embodiment, connecting portions 210 are provided on both opposite sides of the nozzle 200.
[0050] like Figure 1 and Figure 3 As shown, the anti-collision component 100 has a boss structure 118 corresponding to the mounting part 111. The connecting part 210 abuts against the boss structure 118 and is connected to the boss structure 118 by bolts. The boss structure 118 provides locally reinforced support and positioning reference for the connecting part 210. The surface contact abutment effectively disperses the bolt tightening stress and ensures that the nozzle 200 obtains more precise vertical and horizontal position control during installation, thereby improving the rigidity, accuracy and reliability of the connection.
[0051] like Figure 1 As shown, the top plane of the connecting part 210 is lower than the top plane of the anti-collision assembly 100. This arrangement ensures that after the nozzle 200 is installed, its connecting part 210 is completely recessed within the outline of the anti-collision assembly 100, avoiding potential movement interference and collision risks for the installation of other components.
[0052] Some embodiments of this application also provide a printer, including a printhead, a crash barrier, and a printhead 200.
[0053] The printhead 200 is mounted on the anti-collision component 100, which is fixed to the print carriage. This configuration creates a modular assembly system of printhead 200, anti-collision component 100, and print carriage. The anti-collision component 100, which integrates heating and protection functions, is fixed to the print carriage as the core module, enabling rapid disassembly and assembly and overall maintenance of the printer printhead 200 system, while ensuring the coordinated stability of thermal management and mechanical movement during printing.
[0054] It should be noted that the printhead is a common mechanism in existing printers, capable of moving along the X and Y axes to control the movement of multiple printheads 200 to achieve the printing function. Furthermore, the printhead is not an improvement in this embodiment, and its specific structure will not be described in detail here.
[0055] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0056] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.
[0057] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
