Description

Technical Field

[0001] This utility model relates to the field of calendering technology, specifically a calendering machine for thermally conductive silicone. Background Technology

[0002] A calender for thermally conductive silicone is a specialized piece of equipment designed for producing thermally conductive silicone products. Through multiple unwinding mechanisms (such as four substrate unwinding groups), it can simultaneously process materials such as PET film and fiberglass cloth, meeting the bonding requirements of thermally conductive silicone with different substrates. Employing a coating-calendering combination design, it can handle high-viscosity materials ranging from liquid to semi-solid, ensuring molding quality for complex formulations. Semi-fluid silicone is placed between two baffles from one end of the worktable. A rotating pressure roller winds in the fluid silicone, flattens it, and transfers it to the lower end of the subsequent pressure roller. The distance between the two baffles is controlled by a ball screw structure, resulting in a certain gap between the baffle and the worktable below, ensuring smooth baffle movement. Once the baffle reaches the appropriate position, another baffle is fixed to its lower end with screws, fitting snugly against the worktable to ensure the baffle and worktable are aligned and no silicone flows out.

[0003] In existing calenders, adjusting the distance between the two first baffles requires first disassembling and removing the lower second baffle, then reinstalling it after adjustment. This process is complex and time-consuming, impacting overall production efficiency. Therefore, a calender for thermally conductive silicone is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a calender for thermally conductive silicone to solve the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution: This utility model relates to a calendering machine for thermally conductive silicone, comprising: The four-roll calender includes a support base, a working platform, and a first baffle. The working platform is fixed inside the support base, and there are two first baffles that are movably connected above one end of the working platform. The convenient component includes a first opening, a second baffle, a bolt, a first ball bearing, a first U-shaped connecting bracket, and a spring post. The first opening is located in the middle of the first baffle and is symmetrically distributed. The first ball bearing is rotatably connected to the side of the second baffle and fits against the side of the first baffle. One end of the bolt is fixed to the side of the first baffle, and the other end is inserted into the first opening. The first U-shaped connecting bracket is fixed to the middle of the upper part of the second baffle, and one end of the spring post is fixed to the middle of the upper part of the first U-shaped connecting bracket.

[0005] Furthermore, the convenient component also includes a limiting plate, a second opening, and a second ball bearing. The second opening is formed on the limiting plate and is sleeved on the bolt. The second ball bearing is rotatably connected to the side of the limiting plate and fits against the side of the first baffle.

[0006] Furthermore, the convenient component also includes a third ball bearing, which is rotatably connected to the movable end of the spring column.

[0007] Furthermore, the second baffle and the limiting plate are located on both sides of the first baffle, and the bolts are fixed to the first baffle and the limiting plate by nuts.

[0008] Furthermore, there is a gap between the lower end of the first baffle and the working platform, and the second baffle is movably connected to the working platform.

[0009] Furthermore, it also includes a connecting assembly, which includes a second U-shaped connecting frame, a third U-shaped connecting frame, and a connecting rod. The second U-shaped connecting frame is fixed to the upper middle part of one of the first U-shaped connecting frames, the third U-shaped connecting frame is fixed to the upper middle part of the other first U-shaped connecting frame, and one end of the connecting rod is fixed to the upper side of the third U-shaped connecting frame, while the other end is inserted into the inner side of the second U-shaped connecting frame.

[0010] Furthermore, when the lower ends of the two second baffles land on the work platform, the second U-shaped connecting frame is higher than the third U-shaped connecting frame.

[0011] Furthermore, when the movable end of the spring column rests on the upper end of the first baffle, there is a gap between the upper end of the connecting rod and the inner top surface of the second U-shaped connecting frame.

[0012] This utility model has the following beneficial effects: This invention, through a convenient component, allows the side of the limiting plate with the second ball bearing to be attached to the side of the first baffle. After the bolt on the side of the second baffle is passed through the first and second openings and the nut is tightened onto the bolt, before adjusting the distance between the two first baffles, the first U-shaped connecting frame is pulled upwards. This causes the third ball bearing on the spring column to roll against the first baffle, simultaneously moving the second baffle and the limiting plate upwards. The first and second ball bearings roll against the first baffle, while the bolt moves upwards along the first opening. When the movable end of the spring column moves above the first baffle, it extends, releasing the first U-shaped connecting frame. The movable end of the spring column falls onto the upper part of the first baffle, at which point the second baffle separates from the worktable. Rotating the turntable causes the lead screw to rotate, which in turn moves the first and second baffles to the appropriate positions and stops. Pressing the movable end of the spring column and pressing down the first U-shaped connecting frame pushes the lower end of the second baffle against the work platform. This design combines the traditional multi-step disassembly and assembly operation into a single lifting action, significantly shortening the adjustment time. Attached Figure Description

There is a gap between the lower end of the first baffle 12 and the working platform 11, and the second baffle 21 is movably connected to the working platform 11; The support base 10 and the working platform 11 provide support, and the control cabinet is installed on the support base 10 for starting and closing the equipment and setting relevant working parameters. A pressure roller is rotatably connected above the working platform 11 inside the support base 10 for flattening the silicone. The first baffle 12 serves as a limit and moves in a straight line through a turntable and ball screw structure.

[0019] The convenient component includes a first opening 20, a second baffle 21, a bolt 22, a first ball bearing 23, a first U-shaped connecting bracket 27, and a spring post 28. The first opening 20 is located in the middle of the first baffle 12 and is symmetrically distributed. The first ball bearing 23 is rotatably connected to the side of the second baffle 21 and fits against the side of the first baffle 12. One end of the bolt 22 is fixed to the side of the first baffle 12, and the other end is inserted into the first opening 20. The first U-shaped connecting bracket 27 is fixed to the middle of the upper end of the second baffle 21, and one end of the spring post 28 is fixed to the middle of the upper end of the first U-shaped connecting bracket 27. The convenient component also includes a limiting plate 24, a second opening 25, and a second ball 26. The second opening 25 is opened on the limiting plate 24 and is sleeved on the bolt 22. The second ball 26 is rotatably connected to the side of the limiting plate 24 and fits against the side of the first baffle 12. The convenient component also includes a third ball bearing 29, which is rotatably connected to the movable end of the spring column 28; The second baffle 21 and the limiting plate 24 are located on both sides of the first baffle 12, and the bolts 22 are fixed to the first baffle 12 and the limiting plate 24 by nuts; The first opening 20, bolt 22, and second opening 25 serve as a connection, and the first opening 20 facilitates the movement of bolt 22. The second baffle 21 serves as a limit, the limit plate 24 serves as a support, the first ball 23 and the second ball 26 can reduce the frictional resistance when the second baffle 21 and the limit plate 24 move, the first U-shaped connecting frame 27 serves as a support, the spring column 28 has a telescopic function and serves as a limit, and the third ball 29 can reduce the frictional resistance when the spring column 28 moves.

[0020] Working principle: The side of the limiting plate 24 with the second ball bearing 26 is attached to the side of the first baffle 12. The bolt 22 on the side of the second baffle 21 is passed through the first opening 20 and the second opening 25, and the nut is tightened onto the bolt 22. Before adjusting the distance between the two first baffles 12, the first U-shaped connecting bracket 27 is pulled upwards, causing the third ball bearing 29 on the spring column 28 to roll against the first baffle 12. Simultaneously, the second baffle 21 and the limiting plate 24 move upwards, and the first ball bearing 23 and the second ball bearing 26 roll against the first baffle 12. Meanwhile, the bolt 2... 2. Move upward along the first opening 20. When the movable end of the spring column 28 moves above the first baffle 12, the movable end of the spring column 28 extends, releasing the first U-shaped connecting frame 27. The movable end of the spring column 28 falls on the upper end of the first baffle 12. At this time, the second baffle 21 separates from the worktable. Rotate the turntable to drive the lead screw to rotate, thereby driving the first baffle 12 and the second baffle 21 to move to the appropriate position and stop. Press the movable end of the spring column 28 and press down the first U-shaped connecting frame 27 to push the lower end of the second baffle 21 to fit against the work platform 11.

When the lower ends of the two second baffles 21 fall on the working platform 11, the second U-shaped connecting frame 30 is higher than the third U-shaped connecting frame 31; When the movable end of the spring column 28 falls on the upper end of the first baffle 12, there is a gap between the upper end of the connecting rod 32 and the inner top surface of the second U-shaped connecting frame 30. The second U-shaped connecting frame 30, the third U-shaped connecting frame 31, and the connecting rod 32 serve as a connection.

[0023] Working principle: Before adjusting the spacing of the first baffle 12, pull the connecting rod 32 to move the third U-shaped connecting frame 31 upward, and then move the second U-shaped connecting frame 30 upward. When the movable end of the spring column 28 moves above the first baffle 12, the movable end of the spring column 28 extends. Release the connecting rod 32, and the movable end of the spring column 28 falls on the top of the first baffle 12. Rotate the turntable to drive the lead screw to rotate, which in turn drives the first baffle 12 and the second baffle 21 to move. At this time, the second U-shaped connecting frame 30 and the third U-shaped connecting frame 31 move, and the connecting rod 32 moves inside the second U-shaped connecting frame 30.
