A UV transfer printing device suitable for pattern processing on acrylic bathtub surfaces

Abstract

This utility model relates to the technical field of UV transfer printing devices and discloses a UV transfer printing device suitable for processing patterns on the surface of acrylic bathtubs, including a bracket. This UV transfer printing device for processing patterns on the surface of acrylic bathtubs, through the setting of a clamping mechanism, first moves the outer bathtub upwards from the slope next to the base into the inside of the slot. Then, the clamping hydraulic rods on both sides inside the slot are adjusted and fixed to the bottom sides of the outer bathtub by the control of the PLC controller. Next, the upper clamping assembly inside the bracket allows the arc-shaped clamping plate to clamp and fix the outer bathtub to the other two sides of the upper end, thus clamping and fixing the outer bathtub for subsequent work. This avoids the lack of a clamping and fixing link, which can easily lead to positional shifts or shaking, resulting in local suspension or misalignment of force points, easily causing pattern alignment deviations, uneven adhesion of the transfer film, and air bubbles, affecting the transfer quality and even reducing the product yield.

Description

Technical Field

[0001] This utility model relates to the field of UV transfer printing device technology, and in particular to a UV transfer printing device suitable for processing patterns on the surface of acrylic bathtubs. Background Technology

[0002] Acrylic bathtubs have become a mainstream product category in the market due to their many advantages. In order to enhance the aesthetics and added value of the products, the industry generally adopts UV transfer printing technology to process high-precision patterns such as wood grain, stone grain, and metallic texture on their surfaces. Therefore, it is necessary to design a UV transfer printing device suitable for processing patterns on the surface of acrylic bathtubs.

[0003] Traditional devices lack clamping and fixing mechanisms, making them prone to misalignment or displacement of the external bathtub during the transfer process. This can lead to issues such as partial suspension or misalignment of stress points, resulting in misalignment of the pattern, uneven adhesion of the transfer film, and air bubbles. Consequently, the quality of the transfer is affected, and the yield rate of the finished product may even be reduced. Furthermore, the spraying structure of traditional UV transfer devices is mostly fixed-angle spraying, which can only slide horizontally and cannot achieve multi-dimensional position adjustment or angle deflection. This makes it impossible to adapt to the spraying range of bathtubs of different sizes, resulting in uneven paint atomization, "color difference bands," paint waste, and reduced paint quality.

[0017] (III) Beneficial Effects

[0018] This utility model provides a UV transfer printing device suitable for processing patterns on the surface of acrylic bathtubs, which has the following beneficial effects:

[0019] 1. This UV transfer printing device, suitable for processing patterns on the surface of acrylic bathtubs, features a clamping mechanism. During use, a slot is installed inside the base. The outer bathtub is first moved upwards from the slope beside the base into the slot. Then, the clamping hydraulic rods on both sides of the slot, controlled by a PLC controller, adjust the clamping base plate to clamp and fix it to the bottom sides of the outer bathtub. Next, the upper clamping assembly inside the bracket, through an extension hydraulic rod connected by a crossbar, adjusts the extension length, allowing the arc-shaped clamping plate to clamp and fix it to the other two sides of the upper end of the outer bathtub. This effectively clamps and fixes the outer bathtub, facilitating subsequent transfer printing and other processes. It avoids the problems associated with a lack of clamping and fixing, which can lead to positional shifts or shaking, resulting in localized suspension or misalignment of force points. This can cause misalignment of the pattern, uneven adhesion of the transfer film, air bubbles, and affect the quality of the transfer, even reducing the product yield.

[0020] 2. This UV transfer printing device, suitable for processing patterns on the surface of acrylic bathtubs, features an adjustable mechanism. When in use, a lead screw and a limit rod are installed inside the top frame. A drive motor, providing power to move the slide rod left and right, is installed at the right end of the lead screw. A painting assembly is installed outside the slide rod. The rotating shaft and rotary motor inside the painting assembly allow the shaft to move the paint head horizontally and rotate vertically. Furthermore, a lifting hydraulic rod is installed at the top of the paint head, allowing for adjustment of the painting height according to the size and height of the bathtub during left-right movement and rotation. This provides flexible adjustment of the painting angle, avoiding the limitations of traditional painting devices that lack angle adjustment, limiting movement to simple horizontal sliding and preventing multi-dimensional positional adjustment and angle rotation. Such devices cannot adapt to the painting range of different bathtub sizes, resulting in paint waste, reduced painting quality, and a narrower application range. Attached Figure Description
