Description

Technical Field

[0002] Spiral protective sleeves are widely used in construction machinery and injection molding equipment such as excavators, loaders, road rollers, pavers, forklifts, cranes, and dump trucks. Installed on the exterior of hydraulic hoses, wires, and cables, they enhance the wear resistance, antistatic properties, and UV resistance of internal components, providing safety protection in harsh environments. Installing spiral protective sleeves on hydraulic hoses, wires, and cables not only improves aesthetics but also extends the lifespan of internal components, offering broad market prospects. However, traditional printing equipment, typically using flat or roller printing methods, struggles to adapt to the curved surface structure of spiral sleeves, easily resulting in unclear printing and distorted fonts.

[0003] Therefore, there is an urgent need for an integrated production line for spiral protective sleeves that can achieve continuous online automatic printing during the molding process. Utility Model Content

[0030] Example 1:

[0031] In this embodiment, a spiral protective sleeve production line integrating production and printing is described, such as... Figures 1 to 3 As shown, the device includes an extruder 1 for continuously extruding a molten strip 12; a die shaft 2 on which the strip 12 is spirally wound, the die shaft 2 having an inlet end and an outlet end, the extruded strip 12 being wound around the die shaft 2 from the inlet end, rotating and moving around the die shaft 2 and being output from the outlet end; a drive mechanism, the power output end of which is connected to the die shaft 2 to drive the die shaft 2 to rotate in the spiral direction of the strip 12; and an inkjet printer 3 with the printhead 4 aligned with the surface of the strip 12.

[0032] By employing this structure, the rotational speed of the mold shaft 2, the printing speed of the inkjet printer 3, and the production speed of the extruder 1 are coordinated to match each other. This allows the printhead 4 to continuously or intermittently print on the molten material strip 12 during the spiral winding process on the mold shaft 2. After the material strip 12 cools and solidifies, clear, non-deformable, and non-shedding characters can be formed. Production and printing are carried out simultaneously without the need for additional processes, thus improving production efficiency and making this invention more practical.

[0033] In this embodiment, as Figure 1As shown, the nozzle 4 is located above the mold shaft 2. The surface of the nozzle 4 is parallel to the surface of the strip 12 at any position between the extruder 1 and the mold shaft 2. The nozzle 4 prints on the strip 12 in the molten state immediately after extrusion. The strip 12 then wraps around the mold shaft 2 and cools to form, making the printed characters less likely to fall off on the formed strip 12.

[0034] Furthermore, the distance between the surface of the printhead 4 and the surface of the material strip 12 is 10-30mm. The drive mechanism controls the mold shaft 2 to rotate at a uniform speed, so that the output speed of the extruder 1 matches the rotation speed of the mold shaft 2. The ink sprayed from the printhead 4 is sprayed onto the uniformly extruded material strip 12. The text and image format files to be printed are pre-imported into the software of the inkjet printer 3. The printing speed and time interval are adjusted to match the rotation speed of the mold shaft 2. The ink is quick-drying and can be soaked in water. After printing, the marking is checked to see if it is clear. Then, continuous automatic production and printing can be achieved.

[0035] In this embodiment, as Figure 1 As shown, the printhead 4 is connected to the inkjet printer 3 via a metal hose 5. The metal hose 5 can be bent and fixed at will, thereby adjusting the position of the printhead 4 so that the printhead 4 can be aligned with the material strip 12 at any position. A universal joint 6 with a lockable angle is provided between the printhead 4 and the metal hose 5, so that the printhead 4 has multiple degrees of freedom and can be finely adjusted in multiple angle directions at a fixed position, making it more practical. The inkjet printer 3 is an ink small character inkjet printer 3 in the prior art, which has a printhead 4, an ink cartridge and an ink pump. Of course, a laser marking machine with the same inkjet printing function in the prior art can also be selected.

[0036] As one specific implementation method of this embodiment, such as Figure 3 As shown, the mold shaft 2 is an optical shaft, and the material strip 12 is spirally wound on the optical shaft. A traction drum 14 is provided on one side of the discharge end of the mold shaft 2. The traction drum 14 is arranged parallel to the mold shaft 2. The traction drum 14 is used to pull the material strip 12 towards the discharge end of the mold shaft 2. Specifically, the rotation direction of the traction drum 14 is opposite to the rotation direction of the mold shaft 2. The surface of the traction drum 14 is in contact with the surface of the material strip 12 to pull the material strip 12 to move along the direction of the discharge end of the mold shaft 2. The traction drums 14 can be arranged on the left and right at both ends of the mold shaft 2 for better traction effect.

[0037] As another specific implementation of this embodiment, such as Figure 2As shown, the surface of the mold shaft 2 is provided with a spiral groove 7, and the material strip 12 is wound in the spiral groove 7. The spiral groove 7 plays a guiding role for the material strip 12, so that the material strip 12 can rotate along the spiral groove 7 and move towards the discharge end of the mold shaft 2.

[0038] According to a preferred embodiment, such as Figure 1 As shown, the drive mechanism includes a drive motor 8 and a coupling 9. The feed end of the mold shaft 2 is connected to the power output shaft of the drive motor 8 through the coupling 9. The drive motor 8 controls its rotation speed through a frequency converter to achieve synchronous rotation between the drive motor 8 and the mold shaft 2.

[0039] According to another preferred embodiment, such as Figure 2 As shown, the drive mechanism includes a stepper motor 10, a chain 11, and a sprocket 13. The feed end of the mold shaft 2 and the power output shaft of the stepper motor 10 are both equipped with the sprocket 13. The chain 11 is wound around the two sprockets 13. The stepper motor 10 drives the mold shaft 2 to rotate, which has the advantages of higher adjustment accuracy and better system stability. Of course, other transmission mechanisms such as gear transmission can also be used to realize the power transmission between the motor and the mold shaft 2.

[0040] In this embodiment, a spray pipe is also included. Multiple spray pipes are evenly arranged above the mold shaft 2. The spray pipes are used to cool the material strip 12 spirally wound on the mold shaft 2, which can achieve targeted cooling of local high temperature positions and ensure that the quality and performance of the product are uniform.

[0041] As another specific implementation of this embodiment, a cold water tank is also included. Two-thirds of the surface of the mold shaft 2 along the axial direction is immersed below the liquid surface of the cold water tank, thereby preventing the material strip 12 from deforming or twisting due to uneven shrinkage during the cooling process, so that the material strip 12 can be quickly cooled and shaped to form a spiral protective sleeve.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations 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. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
