Description

Technical Field

[0001] This utility model relates to the field of line marking machine technology, and specifically to a line marking machine. Background Technology

[0002] The various styles and patterns of shoes worn in daily life are made by designers who design different shapes and colors of shoe pattern pieces on the shoe upper and then sew them together. In order to achieve the aesthetics and shape consistency of the shoe pattern pieces and to ensure the stability of the quality of mass production of shoes, an important production process is to mark the positioning reference points for the folding and sewing of the shoe upper. Production workers then fold and sew the different shaped pieces of shoe upper according to the marked reference lines to ensure that the same style of shoes made by different production workers have the same shape.

[0003] Existing automated line marking equipment typically includes a conveyor mechanism and an inkjet printing mechanism. The conveyor mechanism transports shoe sole pieces, and the inkjet printing mechanism then marks lines on their surface. However, in practical applications, existing technologies still face several technical challenges that urgently need to be addressed: First, during prolonged operation or standby, the inkjet nozzles are prone to drying or clogging due to ink evaporation, affecting the continuity and accuracy of the lines drawn and reducing the stability of the equipment. Second, during the conveying process, especially for softer or irregularly shaped pieces of shoe upper material, warping, shifting, or wrinkling can occur, leading to inkjet position deviations and affecting the accuracy and consistency of the markings. Utility Model Content

[0004] In view of the prior art, the purpose of this utility model is to provide a line marking machine that can position irregularly shaped materials or soft, easily deformable individual shoe material pieces and solve the problem of inkjet clogging due to drying.

[0005] To address the problems existing in the background technology, this utility model proposes a line marking machine, the technical solution of which is as follows: A line marking machine includes a frame, an outer frame housing, and an operating door and control display unit fixed to the outer frame housing. The frame is provided with a feeding mechanism, a pressing mechanism, and an inkjet mechanism. The pressing mechanism includes a ring-shaped chain belt, a belt-loading chain, and a pressing belt. The two ends of the pressing belt are respectively connected to the belt-loading chain on both sides of the chain belt. The two ends of the pressing belt on the pressing mechanism are staggered and connected to the belt-loading chain on both sides, and the two opposite chain belts are staggered to form a mesh to form a pressing belt mesh. The inkjet mechanism includes a lifting module and an inkjet unit. The lifting module is used to drive the inkjet unit to lift and lower relative to the frame. A moisturizing mechanism is also provided above the feeding mechanism and the pressing belt mesh. The moisturizing mechanism includes a rodless cylinder, an aluminum alloy flow strip, and a moisturizing plate. The rodless cylinder is used to drive the moisturizing plate to move along the aluminum alloy flow strip.

[0006] As a further feature of the above scheme, the pressure belt of the pressure belt mesh is connected to the belt chain plates on both sides, and the middle part of the mesh cross structure formed by them is arranged in a mirror symmetrical manner with the central axis as the central axis.

[0007] As a further provision of the above solution, the lifting module includes a drive unit, a slider, and a slide rail. The inkjet unit is fixed on the slider of the lifting module and is driven by the drive unit to move up and down along the slide rail.

[0008] As a further provision of the above solution, the travel of the humidifying plate includes moving to or completely moving away from the inkjet unit.

[0009] As a further feature of the above solution, the control components of the drive unit and the rodless cylinder are both connected to the control display unit, which is also equipped with a humidification button.

[0010] As a further provision of the above scheme, the inkjet mechanism also includes an ink replenishment mechanism, which includes a primary ink cartridge, a secondary ink cartridge, an air cartridge, and an ink replenishment pump connected to the secondary ink cartridge. The primary ink cartridge is equipped with an inkjet unit for processing, and the secondary ink cartridge is equipped with a liquid level rod and a float.

[0011] As a further feature of the above solution, the moisturizing plate is also provided with a moisturizing component, which includes a silicone sheet and a cashmere cloth that are fixed to the upper surface of the moisturizing plate in sequence.

[0012] Beneficial effects: The pressing mechanism of this utility model forms a mesh pressing belt through interlaced connections, which can uniformly and stably press and fix the entire sheet material during the conveying process. This can prevent soft or irregularly shaped sheets from warping, shifting, and wrinkling, ensuring the accuracy of inkjet line drawing. When the equipment can drive the moisturizing plate to move directly below the inkjet mechanism via a rodless cylinder, the cashmere cloth on the moisturizing plate can remain moist, keeping the nozzles of the inkjet unit moisturized and preventing the ink inside the nozzles from evaporating and drying. When working again, the moisturizing plate can be removed directly, effectively improving the stability of equipment operation and line drawing accuracy, and extending the service life of the nozzles.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0021] like Figure 1-6 The line marking machine shown includes a frame 1, an outer frame housing 2, an operation door 21 and a control display unit 22 fixed to the outer frame housing 2.

[0022] refer to Figure 2 The frame 1 of the present invention shown is also provided with a feeding mechanism 3, a pressing mechanism 4 and an inkjet mechanism 5, and a moisturizing mechanism 6 is provided above the feeding mechanism 3 and the pressing mesh.

[0023] refer to Figure 3 The pressing mechanism 4 shown includes a ring-shaped chain belt 41, a belt-mounting chain piece 42, and a pressing belt 43. The two ends of the pressing belt 43 are respectively connected to the belt-mounting chain pieces 42 on both sides of the chain belt 41. The two ends of the pressing belt 43 on the pressing mechanism 4 are staggered and connected to the belt-mounting chain pieces 42 on both sides, and the two sides of the chain belt 41 are staggered and cross in a mesh to form a pressing belt mesh.

[0024] refer to Figure 4 and Figure 5The inkjet mechanism 5 includes a lifting module 51 and an inkjet unit 52. The lifting module 51 is used to drive the inkjet unit 52 to move up and down relative to the frame 1. The moisturizing mechanism 6 includes a rodless cylinder 61, an aluminum alloy flow strip 62 and a moisturizing plate 63. The rodless cylinder 61 is used to drive the moisturizing plate 63 to move along the aluminum alloy flow strip 62.

[0025] As described above, the marking machine of this utility model has a feeding mechanism 3 and a pressing mechanism 4 mounted on the frame 1 to stably and accurately convey the material sheet. The material sheet is conveyed by a mesh-like pressing belt 43 formed by the pressing belts 43 crisscrossing from both sides towards the center on the pressing mechanism 4. During use, when the inkjet mechanism dries out due to long-term operation or standby, the equipment can trigger a one-button moisturizing function by periodically setting or actively pressing the moisturizing button 23 on the control display unit 22. When the one-key moisturizing function is triggered, the feeding mechanism 3 and the pressing mechanism 4 on the frame 1 remain stationary. At this time, the rodless cylinder 61 of the moisturizing mechanism 6, which is located directly below the inkjet unit 52, is activated, moving the moisturizing plate 63 to directly below the inkjet unit 52. After it is in place, the action stops. Then, the lifting module 51 of the inkjet mechanism 5 is activated, driving the inkjet unit 52 to descend and abut against the moisturizing component 64 on the moisturizing plate 63 through the drive unit 53. The nozzle is moisturized by the moisturizing liquid (water is fine) that has been sprayed on the cashmere cloth 66 of the moisturizing component 64 in advance.

[0026] As a further feature of the above solution, the pressure belt 43 of the pressure belt mesh is connected to the belt chain pieces 42 on both sides. The middle part of the mesh-like cross structure formed by them is arranged in a mirror symmetrical manner with the central axis. In this embodiment, each belt chain piece 42 is provided with a double hole structure, and its two ends are respectively connected to the chains of two chain belts 41. If a pressure belt 43 breaks accidentally, the pressure belt 43 can be quickly repaired and supplemented by using the second hole. Furthermore, the pressure belt 43 in this embodiment forms a mesh-like cross structure, which forms a uniform and stable pressing and fixing of the entire sheet material, which can prevent soft or irregularly shaped sheets from warping, shifting and wrinkling, and ensure the accuracy of the inkjet drawing line position.

[0027] As a further provision of the above solution, the lifting module 51 includes a drive unit 53, a slider 54, and a slide rail 55. The inkjet unit 52 is fixed on the slider 54 of the lifting module 51 and is driven by the drive unit 53 to move up and down along the slide rail 55.

[0028] As a further provision of the above solution, the travel of the moisturizing plate 63 includes moving to or completely moving away from the inkjet unit 52. As described above, the moisturizing mechanism 6 of this embodiment is provided with a moisturizing member 64 that can move relative to the inkjet unit 52, thereby moisturizing or moving the nozzle of the inkjet unit 52 to allow the inkjet mechanism 5 to work normally.

[0029] As a further feature of the above scheme, the control components of the drive unit 53 and the rodless cylinder 61 are both connected to the control display unit 22, and the control display unit 22 is also provided with a moisturizing button 23.

[0030] As a further setting of the above scheme, such as Figure 6 The inkjet mechanism 5 shown in this embodiment also includes an ink replenishment mechanism 7. The ink replenishment mechanism 7 includes a primary ink cartridge 71, a secondary ink cartridge 72, an air box 75, and an ink replenishment pump connected to the secondary ink cartridge 72. The air box 75 is also equipped with an external negative pressure mechanism, which controls the pressure state inside the primary ink cartridge 71 through an air pipe connection. The primary ink cartridge 71 is equipped with an inkjet unit for processing. The secondary ink cartridge 72 is equipped with a glass shell 76 for easy observation. The liquid level rod 73 and float ball 74 are installed inside the secondary ink cartridge 72. With the above structure, during use, the liquid level rod 73 and float ball 74 in the secondary ink cartridge 72 are used to trigger the ink replenishment pump to work and replenish ink to the secondary ink cartridge 72. The ink in the primary ink cartridge 71 is consumed by the inkjet unit during line drawing processing. At the same time, the ink stored in the secondary ink cartridge 72 flows through the ink pipe 77 and automatically enters the primary ink cartridge 71 (the inkjet unit consumes ink while the primary ink cartridge 71 forms a suction force). In this embodiment, the ink replenishment mechanism 7 can provide a stable automatic ink supply for the ink cartridge operation, making the operation of the inkjet mechanism 5 more stable.

[0031] As a further provision of the above solution, the moisturizing plate 63 is also provided with a moisturizing component 64, which includes a silicone sheet 65 and a cashmere cloth 66 that are fixed to the upper surface of the moisturizing plate 63 in sequence.

[0032] The moisturizing mechanism of this utility model has two core uses. First, in standby, shutdown, or similar situations, after a certain period of inactivity via a timer or pre-programmed setting, the moisturizing function is automatically triggered. This drives the moisturizing plate 63 to move directly below the inkjet unit 52 and activates the lifting module 51 to lower the inkjet unit 52, allowing the nozzles to adhere to the cashmere cloth 66, preventing the nozzles and internal ink from drying out. Second, after prolonged use, the moisturizing function can be activated via a pre-programmed setting or by manually pressing the moisturizing button 23. The device then performs the same operation as described above, using the cashmere cloth 66 to adhere to the nozzles (providing a certain wiping effect) to moisturize the nozzles, preventing some nozzles from drying out and becoming clogged. The function can be triggered periodically based on a pre-programmed setting or manually by the operator.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
