Description

Technical Field

[0001] This utility model relates to the field of foam processing equipment technology, and more specifically, to a foam coating line thickness adjustment mechanism. Background Technology

[0002] Foam is a porous elastic material. To enhance its functionality and added value, it often requires precise coating on its surface. Foam coating line is a specialized piece of equipment for achieving this process. It typically consists of a coating roller, a follower roller, and a drive adjustment component. By precisely controlling the gap between the two rollers, the amount of coating transferred to the foam substrate is determined, which directly affects the thickness uniformity and performance of the product.

[0003] In traditional foam coating thickness adjustment mechanisms, the coating roller and the follower roller are usually installed and adjusted independently. Specifically, the coating roller and the follower roller are fixed on the frame by their respective independent lead screws or eccentric mechanisms. When adjusting the spacing, the positions of the two rollers must be adjusted separately and sequentially. This step-by-step adjustment method is cumbersome and inefficient, and it is also difficult to ensure that the axes of the two rollers remain strictly parallel, which ultimately affects the uniformity of coating thickness adjustment.

[0004] In view of this, we propose a foam coating line thickness adjustment mechanism. Utility Model Content

[0005] 1. Technical problems to be solved The purpose of this invention is to provide a foam coating line thickness adjustment mechanism to solve the problem mentioned in the background art that the traditional foam coating line thickness adjustment mechanism requires sequential adjustment of the positions of the coating roller and the follower roller when adjusting the coating thickness, which affects the adjustment efficiency and processing accuracy.

[0006] 2. Technical Solution A foam coating line thickness adjustment mechanism includes a frame and a height-adjustable movable frame slidably connected to the frame. First and second movable blocks with adjustable spacing are slidably connected to both sides of the movable frame. A coating roller is rotatably connected to both first movable blocks. A follower roller for coating the foam is rotatably connected to both second movable blocks. A first motor for driving the coating roller to rotate is fixedly connected to either of the first movable blocks. A second motor for adjusting the spacing between the coating roller and the follower roller is fixedly connected to the frame.

[0007] Preferably, both sides of the movable frame are fixedly connected to a first slider with a T-shaped cross-section, and the frame has two first sliding grooves that are adapted to the size of the first sliders. An electric push rod is fixedly connected to the frame, and the extended end of the electric push rod is fixedly connected to the bottom of the movable frame.

[0008] Preferably, a glue pool is fixedly connected between the two first movable blocks.

[0009] Preferably, a second slider and a third slider with a T-shaped cross-section are fixedly connected to both sides of the first movable block and the second movable block. A second slide groove adapted to the size of the second slider is provided on the frame, and a third slide groove adapted to the size of the third slider is provided on the movable frame.

[0010] Preferably, both sides of the frame are rotatably connected to bidirectional screws, the threads at both ends of the bidirectional screws are reversed, and both ends of the bidirectional screws are connected to threaded sleeves through ball screw pairs. The two threaded sleeves are fixedly connected to the first movable block and the second movable block respectively, so that the distance between the coating roller and the follower roller can be adjusted when the bidirectional screws rotate.

[0011] Preferably, drive rods are rotatably connected to both sides of the frame, the top of either drive rod is fixedly connected to the output end of the second motor, the two drive rods are connected by a synchronous belt drive, and the two drive rods are also connected by a synchronous belt to the bidirectional screw on the same side of the frame.

[0013] 3. Beneficial effects Compared with existing technologies, the advantages of this utility model are: 1.

This utility model uses an electric push rod to drive the movable frame to raise and lower the coating roller and the follower roller as a whole, which solves the problems of cleaning difficulties and limited maintenance space caused by the fixed positions of the coating roller and the follower roller in the existing equipment.

[0017] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-6 This utility model provides a technical solution: A foam coating line thickness adjustment mechanism includes a frame 1 and a height-adjustable movable frame 2 slidably connected to the frame 1. The two sides of the movable frame 2 are slidably connected to the frame 1, allowing the movable frame 2 to move up and down relative to the frame 1, thereby synchronously adjusting the height of the coating roller 3 and the follower roller 5. In specific implementation, it is necessary to ensure that the installation position of the movable frame 2 does not affect the coating process. Both sides of the movable frame 2 are slidably connected to adjustable first movable blocks 11 and second movable blocks 12. The two first movable blocks 11 are rotatably connected to the coating roller 3, and the two second movable blocks 12 are rotatably connected to... There is a follower roller 5 for coating foam in conjunction with the coating roller 3. A first motor 7 for driving the coating roller 3 to rotate is fixedly connected to either of the two first movable blocks 11. A first bevel gear 21 is fixedly connected to the output end of the first motor 7. A second bevel gear 22 that meshes with the first bevel gear 21 is fixedly connected to the end of the coating roller 3. A second motor 8 for adjusting the distance between the coating roller 3 and the follower roller 5 is also fixedly connected to the frame 1. That is, the first motor 7 is used to drive the coating roller 3 to rotate for continuous coating of foam, while the second motor 8 is used for thickness adjustment.

[0020] The movable frame 2 has two fixedly connected first sliders 9 with a T-shaped cross section. The frame 1 has two first slide grooves 10 that are adapted to the size of the first sliders 9. An electric push rod 6 is fixedly connected to the frame 1. The extended end of the electric push rod 6 is fixedly connected to the bottom of the movable frame 2. In specific implementation, the fixed connection position between the electric push rod 6 and the movable frame 2 should be located in the middle of the movable frame 2 to ensure the stability of the frame 1 in vertical adjustment. With this setting, the height of the coating roller 3 and the follower roller 5 can be adjusted at the same time, which is more convenient for subsequent maintenance operations.

[0021] In addition, the two ends of the glue pool 4 are fixedly connected to two first movable blocks 11, so that when the distance between the two rollers is adjusted, the first movable blocks 11 will drive the coating roller 3 and the glue pool 4 to move together, thereby keeping the relative position between the glue pool 4 and the coating roller 3 unchanged, so that the position of the glue pool 4 does not need to be readjusted after the distance is adjusted.

[0022] Furthermore, the first movable block 11 and the second movable block 12 are both fixedly connected to a second slider 13 and a third slider 15 with a T-shaped cross section. The frame 1 is provided with a second slide groove 14 that matches the size of the second slider 13, and the movable frame 2 is provided with a third slide groove 16 that matches the size of the third slider 15. The arrangement of the two sets of T-shaped sliders and slide grooves can prevent the first movable block 11 and the second movable block 12 from shifting during movement, ensuring that the axes of the coating roller 3 and the follower roller 5 are always in a parallel state.

[0023] Secondly, both sides of the frame 1 are rotatably connected to bidirectional screws 17. The threads at both ends of the bidirectional screws 17 are reversed, and both ends of the bidirectional screws 17 are connected to threaded sleeves through ball screw pairs. The two threaded sleeves are fixedly connected to the first movable block 11 and the second movable block 12, respectively. This allows the bidirectional screws 17 to adjust the gap between the coating roller 3 and the follower roller 5 when they rotate. With this configuration, when the bidirectional screws 17 rotate, the two threaded sleeves will move synchronously towards or away from each other due to the opposite direction of their threads. This will drive the coating roller 3 and the follower roller 5 to move closer or further away at the same speed, enabling precise gap positioning between the coating roller 3 and the follower roller 5. This ensures that the movement of the coating roller 3 and the follower roller 5 is synchronous and symmetrical, solving the problem that it is difficult to ensure the parallelism between the rollers when adjusting them independently in sequence, and ensuring the uniformity of coating.

[0024] Furthermore, drive rods 18 are rotatably connected to both sides of the frame 1. The top of either drive rod 18 is fixedly connected to the output end of the second motor 8. The two drive rods 18 are connected by a synchronous belt 19. The two drive rods 18 are also connected by a synchronous belt 19 to a bidirectional screw 17 on the same side. The synchronous rotation of the two bidirectional screws 17 by the synchronous belt 19 can ensure the synchronicity of the up and down movement of the coating roller 3 and the follower roller 5 on both sides, and prevent jamming.

[0025] Working principle: When using the device, the first motor 7 drives the coating roller 3 to rotate via the first bevel gear 21 and the second bevel gear 22 to complete the continuous coating of foam. When it is necessary to adjust the coating thickness, the second motor 8 is started. The second motor 8 drives the drive rods 18 on both sides of the frame 1 to rotate via the synchronous belt 19, which in turn drives the bidirectional screws 17 on both sides to rotate synchronously. Since the threads at both ends of the bidirectional screws 17 are reversed, the first movable block 11 and the second movable block 12 fixed on the screw sleeve move in opposite directions or in a straight line, thereby precisely adjusting the gap between the coating roller 3 and the follower roller 5. When it is necessary to perform equipment maintenance or cleaning, the electric push rod 6 is started. The extended end of the electric push rod 6 pushes or pulls the movable frame 2, causing the movable frame 2 to rise or fall along the frame 1, thereby driving the coating roller 3, the follower roller 5 and the glue tank 4 on it to move away from the working height together, providing space for maintenance operations.
