Description

Technical Field

[0001] The utility model relates to the technical field of acrylic sheet production, in particular to a calender for acrylic sheet production. Background Art

[0002] Acrylic sheet, also known as plexiglass sheet, is a plastic material with excellent transparency and weather resistance, and is widely used in fields such as billboards, display stands, interior decoration, fixture manufacturing, lamps, and aquariums. During the production process, the acrylic sheet needs to undergo a calendering process, where the acrylic sheet material is extruded and calendered to obtain the required thickness and surface quality. Therefore, the calender becomes one of the crucial equipment in the acrylic sheet production process.

[0003] However, although the traditional calender has the ability to extrude and form the acrylic sheet material, it cannot adjust different thicknesses. When acrylic sheets of different thicknesses are required, the machine needs to be stopped to replace the rollers, resulting in too low work efficiency. Even though a small number of calenders can adjust the thickness, their operation is complex and the accuracy is poor. At the same time, during the calendering process, the rollers are prone to adhesion to the acrylic sheet material, affecting the subsequent processing quality and production efficiency. Therefore, in view of this, the utility model proposes a calender for acrylic sheet production to improve the problems that the existing calender cannot adjust the thickness and the rollers are prone to adhesion to the acrylic sheet material. Content of the Utility Model

[0004] In order to overcome the shortcomings that the existing calender cannot adjust the thickness and the rollers are prone to adhesion to the acrylic sheet material, the purpose of the utility model is to provide a calender for acrylic sheet production.

[0005] A calender for acrylic sheet production includes a workbench, a base, a top shell, an upper roller, a lower roller, a scale plate, a pointer, a motor, an electric push rod, a water tank, a micro water pump, a spray head, and a conveying component. A first groove is provided in the middle of the workbench. A base is fixedly connected to the upper part of the first groove. The top shell is slidably connected to the upper part of the base. Electric push rods are fixedly installed at the four corners inside the base, with the telescopic rods of the electric push rods facing upwards, and the telescopic rods of the electric push rods are fixedly connected to the top shell.

Motors are fixedly installed at the rear parts of the base and the top shell, and the output shafts of the upper and lower motors are respectively fixedly connected to the upper roller and the lower roller. At least one scale plate is fixedly connected to the front and rear sides of the base, and the scale plate is slidably connected to the top shell. At least one pointer is fixedly connected to the front and rear sides of the top shell, and the pointer points to the scale plate. A water tank is fixedly connected to the lower part of the first groove. The water tank is divided into left and right compartments, and at least two micro water pumps are fixedly connected to both the left and right compartments. The upper part of the micro water pump is fixedly installed with a spray head. The left compartment of the water tank is filled with stripping liquid. Conveying components are fixedly connected to both the left and right parts of the base.

[0006] Optionally, a second groove is provided in the middle of the workbench. The second groove is located directly above the right compartment of the water tank and has the same size as the right compartment of the water tank. The right compartment of the water tank is filled with coolant.

[0007] Optionally, a spirit level is further included. A groove is provided in the middle of the pointer, and the spirit level is fixedly connected inside the groove.
