Description

Technical Field

[0001] This utility model relates to the field of thermoforming bathtub processing technology, specifically a thermoforming bathtub surface trimming mechanism. Background Technology

[0002] Bathtubs are a common bathroom product, and they are made of a variety of materials. Acrylic is widely used because of its lightweight and low price. Acrylic bathtubs are made of a mixture of plastic materials.

[0003] A search revealed that the existing technology, specifically the authorized patent CN223173077U, discloses a thermoforming bathtub skin trimming mechanism. This mechanism includes a bathtub body and a cutting section disposed on the bathtub body. It further includes: a base plate with a second sliding groove along its edge, to which the bathtub body is fixed; a clamping unit symmetrically disposed on the base plate and cooperating with the bathtub body; and a support frame slidably disposed within the second sliding groove. The cutting unit includes a cutting blade, a first motor, and a slider slidably disposed on the support frame. The thermoforming bathtub skin trimming mechanism provided by this invention fixes the bathtub body to the base plate via the clamping unit. Then, a transmission unit controls the cutting blade to approach the bathtub, and the first motor is activated to rotate the cutting blade and cut the bathtub body. Simultaneously, the support frame slides along the second sliding groove around the base plate, thereby quickly and accurately removing the cut section, improving cutting efficiency and precision.

[0004] However, the above technical solutions still have the following shortcomings in use: the devices can only perform edge trimming on specific models of vacuum-formed bathtubs and cannot be applied to vacuum-formed bathtubs of various sizes and specifications, resulting in poor applicability. This leads to manufacturers needing to equip themselves with multiple edge trimming devices during actual production, resulting in higher costs. To address this, we propose a vacuum-formed bathtub surface edge trimming mechanism to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting mechanism for the surface of a vacuum-formed bathtub to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermoforming bathtub skin trimming mechanism, comprising: A base is provided, on which a support column is rotatably mounted.

A movable seat is slidably connected to the fixed rod. A fixed box is fixedly welded to the bottom end of the movable seat. A dual-axis motor is fixedly installed in the inner cavity of the fixed box. Two first screws are drivenly connected to the dual-axis motor. Guide rods are provided on both sides of the first screws. The guide rods are fixedly welded to the fixed box. A movable plate is threadedly connected to the first screw. The movable plate is slidably connected to the guide rods. An installation plate is provided on the movable plate. A drive motor is fixedly installed on the installation plate. A cutting blade is installed on the drive motor.

[0007] Preferably, a second screw is provided above the fixed rod, the second screw is rotatably mounted on the back plate, a first servo motor is fixedly mounted on the rear side wall of the back plate, the output end of the first servo motor is drivenly connected to the second screw, and the movable seat is threadedly connected to the second screw.

[0008] Preferably, both movable plates are provided with through slots, a pair of fixed posts are fixedly welded in the through slots, the mounting plate is slidably connected to the pair of fixed posts, an electric telescopic rod is fixedly installed in the through slots, and the output end of the electric telescopic rod is fixedly installed on the mounting plate.

A first gear is fixedly installed on the shaft of the second servo motor, and a second gear is fixedly installed on the support column. The second gear meshes with the first gear.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention allows the first servo motor to drive the second screw to rotate, causing the movable seat to move back and forth on the fixed rod, thereby moving the two cutting blades to cut. The dual-axis motor can drive the first screw to rotate, causing the two movable plates to move towards or away from each other, thus adjusting the distance between the two cutting blades. This facilitates cutting the surface of various sizes of thermoformed bathtubs. The second servo motor can drive the support column to rotate, which in turn drives the tray to rotate, making it easier to rotate and adjust the position of the thermoformed bathtub body. This allows for easy replacement of the cutting edge position of the thermoformed bathtub body. Furthermore, the simultaneous cutting of the two cutting blades allows for cutting the surface on both sides at the same time, improving cutting efficiency. Attached Figure Description
