Description

Technical Field

[0001] This application relates to the field of calendering equipment, and more particularly to a rolling calendering apparatus. Background Technology

[0002] In the existing field of calendering equipment technology, various calendering devices are widely used in the materials processing industry to calender materials such as plastics, rubber, and metals. Traditional calendering equipment mostly uses a fixed calendering roll configuration, which cannot flexibly adjust the spacing between the calendering rolls according to actual processing needs, resulting in difficulty in ensuring the uniformity of the calendered product thickness. Furthermore, due to the uneven pressure distribution on the material during calendering, product quality is often unstable, reducing production efficiency and product qualification rate.

[0003] To address the aforementioned issues, an adjustable triaxial calender (publication number CN218111808U) has emerged on the market. Its structure includes a mounting base, a first roller, a second roller, and a moving arm. This calender adjusts the distance between the first and second rollers by sliding the moving arm longitudinally on the mounting base, adapting to the calendering requirements of products with varying thicknesses. The portions of the first and second rollers extending beyond the mounting position serve as the first and second calendering surfaces of the calendered product, while the portions extending into the mounting position are rotatably connected to the mounting base and the moving arm, respectively. This design allows the product to flow in the same direction during calendering, improving calendering efficiency. However, while this calender addresses the distance adjustment issue to some extent, it still has some shortcomings. Because the material exerts significant pressure on the rollers during calendering, and this pressure is distributed along the length of the rollers, the moving arm, under prolonged vertical load, may experience uneven stress, leading to wobbling or jamming. This can affect the uniformity of the calendered product's thickness and may also accelerate equipment wear and aging, reducing the equipment's lifespan.

[0004] Therefore, there is a need for a rolling calendering device that prevents uneven force distribution, swaying, or jamming that may occur when the rollers are subjected to vertical loads during calendering. Utility Model Content

[0005] In view of this, it is necessary to provide a rolling calendering device that prevents uneven force distribution, swaying, or jamming that may occur when the rollers are subjected to vertical loads during calendering, in order to solve the above problems.

[0008] A fixing member is provided, which is clamped between the two mounting brackets, and the fixing member and the moving groove are located in the same vertical extending direction;

[0009] A calendering roll is sandwiched between the two mounting frames. The calendering roll includes a calendering assembly and a moving rod. The calendering assembly is disposed along the length of the moving rod. The moving rod is rotatably connected to the fixing member. The calendering assembly is slidably disposed on the moving groove so that when the moving rod is rotated, the calendering assembly moves in the vertical direction.

[0015] In at least one embodiment of this application, the first positioning plate is further provided with a second positioning hole, which is disposed opposite to the moving groove;

[0016] The limiting member has one end that slides in the moving groove and the other end that extends into the second positioning hole to restrict the movement of the first positioning plate.

[0017] In at least one embodiment of this application, the rolling calendering apparatus further includes a second calendering roller and a third calendering roller, both of which are sandwiched between the two mounting frames and are spaced apart. The calendering roller is arranged alternately between the second calendering roller and the third calendering roller.

[0018] In at least one embodiment of this application, the mounting frame includes a support frame and a support plate disposed on the support frame;

The calendering roller employs a combined design of the calendering assembly and a moving rod. The moving rod is rotatably connected to the fixed component, converting the rotational motion into the vertical linear motion of the calendering assembly, thus avoiding the swaying problem caused by the conflict between horizontal force and vertical adjustment direction in traditional sliding arms.

[0029] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component.

[0031] Embodiments of this application provide a rolling calendering apparatus, comprising:

[0032] Mounting brackets, two of which are spaced apart, and each mounting bracket has a moving groove formed in the vertical direction;

[0033] A fixing member is provided, which is clamped between the two mounting brackets, and the fixing member and the moving groove are located in the same vertical extending direction;

[0034] A calendering roll is sandwiched between the two mounting frames. The calendering roll includes a calendering assembly and a moving rod. The calendering assembly is disposed along the length of the moving rod. The moving rod is rotatably connected to the fixing member. The calendering assembly is slidably disposed on the moving groove so that when the moving rod is rotated, the calendering assembly moves in the vertical direction.

[0035] The aforementioned rolling calendering apparatus, by setting two spaced-apart mounting frames with vertical moving grooves on them, allows the calendering assembly to slide vertically. Simultaneously, a fixed component extends in the same direction as the moving groove, forming a closed rigid frame, significantly enhancing the overall compressive strength and stability of the equipment. The calendering roller employs a combined design of the calendering assembly and a moving rod. The moving rod is rotatably connected to the fixed component, converting the rotational motion into the vertical linear motion of the calendering assembly, thus avoiding the swaying problem caused by the conflict between horizontal force and vertical adjustment direction in traditional sliding arms.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] according to Figures 1-3 This application provides a rolling calendering apparatus 100, comprising: a mounting frame 10, two mounting frames 10 being spaced apart, each mounting frame 10 having a moving groove 10a formed in a vertical direction; a fixing member 20, the fixing member 20 being clamped between the two mounting frames 10, the fixing member 20 and the moving groove 10a being located in the same vertical extension direction; and a calendering roller 30, clamped between the two mounting frames 10, the calendering roller 30 including a calendering assembly 31 and a moving rod 32, the calendering assembly 31 being disposed along the length direction of the moving rod 32, the moving rod 32 being rotatably connected to the fixing member 20, and the calendering assembly 31 being slidably disposed on the moving groove 10a so that when the moving rod 32 is rotated, the calendering assembly 31 moves in a vertical direction.

[0038] Specifically, the mounting frame 10 provides a stable support structure for the entire rolling calendering apparatus. The vertically formed moving groove 10a guides and restricts the vertical movement of the calendering assembly 31, providing guidance and a path for its vertical movement, ensuring that the calendering assembly 31 can move smoothly along a preset path during calendering and avoiding horizontal deviation. During the calendering process, the calendering assembly 31 moves vertically under the guidance of the moving groove 10a, realizing the calendering operation of the material.

[0039] Furthermore, the fixing member 20 serves as a fulcrum for the rotatable connection between the moving rod 32 and the calendering roller 30, ensuring the stability of the calendering roller 30 during rotation. This ensures that the calendering assembly 31 can effectively cooperate with the fixing member 20 during movement, preventing wobbling. Through its rotatable connection with the moving rod 32, the fixing member 20 can control the movement of the calendering assembly 31. When the moving rod 32 rotates, the calendering assembly 31 moves up and down along the direction of the moving groove 10a.

[0040] Furthermore, the calendering roll 30 can directly apply a uniform and stable calendering force to the material to achieve calendering operations. The calendering assembly 31 is located along the length of the moving rod 32 and is used to directly apply calendering force to the material. The moving rod 32 is rotatably connected to the fixed member 20, allowing the calendering assembly 31 to move vertically.

[0041] In summary, the moving rod 32 is rotated according to the thickness requirements of the material to be calendered. The rotation of the moving rod 32, guided by the fixing member 20, is converted into the vertical movement of the calendering assembly 31 within the moving groove 10a. The vertical movement of the calendering assembly 31 changes the distance between the two calendering rollers 30 to accommodate materials of different thicknesses. The material undergoes calendering under the action of the calendering rollers 30 to achieve the required thickness and surface quality. This solves the problem of conflict between the horizontal force and vertical adjustment direction of the traditional sliding arm, and avoids the moving assembly directly bearing lateral force.

[0042] In one specific embodiment, the fixing member 20 has a rotating hole 20a formed along the height direction. The rotating hole 20a and the moving groove 10a are located in the same vertical extension direction, and the moving rod 32 extends into the rotating hole 20a and is threaded into the rotating hole 20a.

[0043] Specifically, the rotating hole 20a allows the moving rod 32 to rotate along the axial direction (i.e., the height direction) of the hole. This is the core mechanism for adjusting the spacing of the calendering rolls 30, enabling the moving rod 32 to achieve the desired adjustment effect through rotation, thus increasing the adjustability and functionality of the equipment. The threaded engagement between the moving rod 32 and the rotating hole 20a means that the moving rod 32 can not only move axially within the hole but also move up and down through rotation. The threaded connection provides stable connection force and adjustment accuracy.

[0044] Furthermore, the rotating hole 20a and the moving groove 10a are located in the same vertical extending direction, so that the pressure roller assembly sliding in the moving groove 10a is also in the same vertical extending direction as the rotating hole 20a. The sliding of the pressure roller assembly in the moving groove 10a and the rotation of the moving rod 32 in the rotating hole 20a are synchronous and interdependent. The rotation of the moving rod 32 is converted into the movement of the pressure roller assembly through the threaded engagement, so that the up and down movement of the moving rod 32 can directly and smoothly drive the pressure roller assembly to slide in the moving groove 10a.

[0045] In one specific embodiment, the calendering assembly 31 includes a calendering frame 311 and a first calendering roller 312. The calendering frame 311 slides between the two mounting frames 10, and the calendering frame 311 is disposed opposite to the moving groove 10a. The calendering frame 311 includes a first positioning plate 3111, a second positioning plate 3112, and a third positioning plate 3113. The first calendering roller 312 is sandwiched between the second positioning plate 3112 and the third positioning plate 3113. The second positioning plate 3112 and the third positioning plate 3113 are disposed adjacent to the first positioning plate 3111, and the first positioning plate 3111 can abut against the fixing member 20. The moving rod 32 is connected to the first positioning plate 3111.

[0046] Specifically, the calender 311 serves as a support and guide structure, while the first calendering wheel 312 directly participates in the calendering process. Through the cooperation of the calender 311 and the first calendering wheel 312, the calendering of the material can be achieved. The calender 311 is allowed to slide freely between the two mounting frames 10, facilitating the adjustment of the calender assembly 31 via the moving rod 32, and allowing for timely adjustment of the position and force of the calendering wheel on the calendered material. The moving groove 10a provides a sliding track for the calender 311 and the calendering wheel. The vertical sliding of the calender 311 is limited by the moving groove 10a of the mounting frame 10, ensuring the straightness and stability of the calendering wheel's movement trajectory.

[0047] Furthermore, the first positioning plate 3111, the second positioning plate 3112, and the third positioning plate 3113 together constitute the main structure of the calender 311. The first positioning plate 3111 serves as the main support plate 12 of the calender 311, connecting to the moving rod 32 and transmitting driving force, providing stable support for the calendering wheel. The second positioning plate 3112 and the third positioning plate 3113 clamp and fix the first calendering wheel 312, restricting its axial and radial displacement. The double positioning plates form a "clamping cavity," ensuring that the calender 311 clamps the calendering wheel axis vertically with the moving groove 10a, preventing skewing during calendering.

[0048] Furthermore, the rotational motion of the moving rod 32 is converted into the linear motion of the first positioning plate 3111 through a threaded structure. The rotational motion of the moving rod 32 is converted into the vertical linear motion of the first positioning plate 3111 through a threaded pair or gear structure.

[0049] In one specific embodiment, the first positioning plate 3111 has a first positioning hole 3111a. The first positioning hole 3111a is located at the center of symmetry of the first positioning plate 3111 along the horizontal direction and is disposed opposite to the moving rod 32. One end of the moving rod 32 includes a locking member 321, which extends into the first positioning hole 3111a to fix the first positioning plate 3111 and the moving rod 32.

[0050] Specifically, the first positioning plate 3111 serves as a reference and support structure to ensure that the moving rod 32 can be positioned accurately and stably. The first positioning hole 3111a is a key element in this positioning process, providing a clear and insertable fixing point for the moving rod 32. The position of the first positioning hole 3111a (at the center of symmetry in this example) ensures the balance and stability of the moving rod 32 during rotation and movement, reducing errors or malfunctions caused by inaccurate positioning.

[0051] Furthermore, the locking component 321 can be a bolt, screw, or other similar structure. The moving rod 32, as a connecting and transmission component at one end, is responsible for directly transmitting the up-and-down movement trajectory of the moving rod 32 to the first positioning plate 3111 connected to the moving rod 32 when it rotates up and down. This, in turn, drives the entire calendering wheel to move up and down via the first positioning plate 3111. The locking component 321 is crucial for connecting the moving rod 32 and the first positioning plate 3111. It achieves a secure connection between the two by extending itself into the first positioning hole 3111a. This ensures the relative position stability between the moving rod 32 and the first positioning plate 3111, preventing performance problems caused by loosening or displacement.

[0052] In one specific embodiment, the first positioning plate 3111 is further provided with a second positioning hole 3111b, which is disposed opposite to the moving groove 10a; the limiting member 40 has one end sliding in the moving groove 10a and the other end extending into the second positioning hole 3111b to restrict the movement of the first positioning plate 3111.

[0053] Specifically, the moving groove 10a serves as the vertical trajectory for restricting the movement of the rolling mill frame 311 on the mounting plate. The first positioning plate 3111 acts as a structural support and positioning reference, and its second positioning hole 3111b cooperates with the limiting member 40 to achieve precise control of the movement of the first positioning plate 3111 by the moving groove 10a. The limiting member 40 can be a bolt, screw, or limiting rod, and the diameter of the end of the limiting member 40 that slides within the moving groove 10a is less than or equal to the horizontal diameter of the moving groove 10a, so that the limiting member 40 can extend into the moving groove 10a and slide.

[0054] Furthermore, the end of the limiting member 40 extending into the second positioning hole 3111b serves to fix and limit the movement, ensuring the connection between the limiting member 40 and the first fixed plate, and the stability of the first positioning plate 3111 during movement. The second positioning hole 3111b is located at a specific position on the first positioning plate 3111, ensuring that when one end of the limiting member 40 slides into the moving groove 10a, the other end can be accurately aligned and fixed in the second positioning hole 3111b, ensuring that the limiting member 40 can properly restrict the movement of the first positioning plate 3111.

[0055] In one specific embodiment, the rolling calendering device further includes a second calendering roller 50 and a third calendering roller 60, both of which are sandwiched between the two mounting frames 10 and are spaced apart. The calendering roller 30 is arranged alternately between the second calendering roller 50 and the third calendering roller 60.

[0056] Specifically, in this embodiment, the second calendering roller 50 and the third calendering roller 60 are mounted between two mounting brackets 10. This layout allows the two calendering rollers to be stably supported within the structural frame of the equipment and to work in conjunction with the first calendering roller 312. When the moving rod 32 moves up and down, the distance between the calendering roller and the second and third calendering rollers 50 and 60 is adjusted, ensuring that the second and third calendering rollers 50 and 60 are on the same horizontal line. By placing the calendered material on the second and third calendering rollers 50 and adjusting the distance between the calendering roller and the second and third calendering rollers 60, the thickness requirements of different calendered materials can be accommodated.

[0057] In one specific embodiment, the mounting frame 10 includes a support frame 11 and a support plate 12 disposed on the support frame 11; wherein, the support plate 12 has a fixed part 121 and a movable part 122 connected to the fixed part 121, the fixed part 121 is disposed on the support frame 11, the fixing member 20 is disposed on the fixed part 121, the movable groove 10a is formed on the movable part 122, and the calendering assembly 31 slides on the movable part 122.

[0058] Specifically, the mounting frame 10 serves as the support and positioning base for the calendering assembly 31, ensuring the stability of the calendering operation. The mounting frame 10 consists of a support frame 11 and a support plate 12, forming a stable and adjustable support system. The fixing part 121 serves as the connection point between the support plate 12 and the support frame 11, ensuring that the support plate 12 is stably mounted on the support frame 11 via the fixing part 121. It is typically an integral part of the support plate 12.

[0059] Furthermore, the movable part 122 is connected to the fixed part 121, but has a certain degree of mobility relative to the fixed part 121. This design allows the calendering assembly 31 to slide and adjust on the movable part 122 of the support plate 12 to adapt to different calendering requirements.

[0060] Furthermore, the fixing member 20 is mounted on the fixing part 121 to ensure that the relative position of the fixing member 20 and the moving part 122 on the support plate 12 is in the same vertical direction, thereby ensuring that the force exerted by the moving rod 32 on the calendering roll is subjected to pressure from the vertical direction. A moving groove 10a is formed on the moving part 122, providing a sliding track for the calendering assembly 31. Through the moving groove 10a, the calendering assembly 31 can slide linearly on the support plate 12.

[0061] In one specific embodiment, the fixing part 121 has a first fixing hole 121a, the fixing member 20 has a second fixing hole 20b, and the support frame 11 has a third fixing hole 11a. Screws pass through the first fixing hole 121a, the second fixing hole 20b, and the third fixing hole 11a to fix the support plate 12, the support frame 11, and the fixing member 20.

[0062] Specifically, the first fixing hole 121a is formed on the fixing part 121 of the support plate 12, serving as a channel connecting the support plate 12 and the fixing member 20. It allows fasteners such as screws to pass through, firmly fixing the fixing member 20 to the support plate 12. The design of the first fixing hole 121a makes the connection between the fixing member 20 and the support plate 12 more stable and reliable, capable of withstanding various forces and vibrations generated during the rolling process, ensuring the smooth progress of the rolling operation. The second fixing hole 20b is formed on the fixing member 20, aligned with the first fixing hole 121a, together forming a channel for the screw to pass through. It ensures that the fixing member 20 can be accurately positioned on the support plate 12 and fastened by screws. The design of the second fixing hole 20b improves the accuracy and stability of the fixing member 20 installation, avoiding a decrease in rolling accuracy or safety hazards caused by positional deviations of the fixing member 20. The third fixing hole 11a is formed on the support frame 11, aligned with the first fixing hole 121a and the second fixing hole 20b, forming a complete screw channel. It allows screws to pass through all components, securely connecting the support plate 12, support frame 11, and fastener 20 together.

[0063] In one specific embodiment, the support frame 11 has an inverted "U" shape, and the support plate 12 has a sheet-like structure.

[0064] Specifically, the inverted "U"-shaped structure has two parallel sidewalls and a connecting wall connecting these two sidewalls, forming an open space that facilitates the installation and adjustment of the calendering assembly 31. The fastener 20 and other components connected to it are mounted on the connecting wall connecting the two sidewalls. The second calendering roller 50 and the third calendering roller 60 are respectively positioned on the two parallel sidewalls, simplifying the overall structure. The support plate 12 adopts a sheet-like structure design, its main function being to provide a flat and stable support surface for installing and fixing the calendering assembly 31. The sheet-like structure has a uniform thickness and a flat surface, ensuring the stability and accuracy of the calendering assembly 31 on the mounting frame 10.

[0065] In one specific embodiment, the movable rod 32 further includes a rotating rod 322, which is located at the end of the movable rod 32 away from the locking member 321, and the rotating member is intersecting with the movable rod 32.

[0066] Specifically, the movable rod 32 is the key component responsible for movement and force transmission in the entire mechanism. It engages with the rotating hole 20a in the fixed member 20 via a threaded structure on the movable rod 32. The rotating rod 322 is located at the end of the movable rod 32 furthest from the locking member 321, and its main function is to increase the flexibility of the mechanism. Rotation of the rotating rod 322 enables movement of the threaded structure on the movable rod 32 that engages with the rotating hole 20a. The intersection of the rotating member and the movable rod 32 facilitates the rotational movement of the movable rod 32 via the rotating rod 322.

[0067] Therefore, the aforementioned rolling calendering apparatus 100, by setting two spaced-apart mounting frames 10 and opening vertical moving grooves 10a on the mounting frames 10, allows the calendering assembly 31 to slide in the vertical direction. Simultaneously, the fixing member 20 extends in the same direction as the moving groove 10a, forming a closed rigid frame, significantly enhancing the overall compressive strength and stability of the equipment. The calendering roller 30 adopts a combined design of the calendering assembly 31 and the moving rod 32. The moving rod 32 is rotatably connected to the fixing member 20, converting the rotational motion into the vertical linear motion of the calendering assembly 31, avoiding the swaying problem caused by the conflict between horizontal force and vertical adjustment direction in traditional sliding arms.

[0068] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
