Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flooring fabric drying equipment, specifically to a flooring fabric unwinding mechanism. Background Technology
[0002] Floor covering is a material used to cover and decorate floors. Rubber floor covering has a strong odor after production and needs to be aired out before use. Since rubber is usually stored in rolls, it needs to be unrolled before drying. Because rubber floor covering will remain curled up when unrolled without external interference, it is not conducive to proper drying.
[0003] In existing technologies, unwinding devices typically use upper and lower pressure rollers for leveling. However, for rubber flooring fabrics, relying solely on roller pressure for leveling requires significant force, which can easily affect the thickness of the flooring fabric and may even cause it to stretch, thus compromising its mechanical properties. Conversely, if the leveling pressure is too low, the rubber flooring fabric can easily rewind after passing through the leveling rollers, which is detrimental to subsequent drying. Utility Model Content
[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a flooring roll unrolling mechanism, which solves the technical problem of incomplete unrolling of flooring fabric in the prior art.
[0005] A floor roll laying mechanism, comprising: The frame is rotatably equipped with an unwinding assembly for placing the flooring roll and a traction assembly for pulling the flooring roll away from the unwinding assembly; A rotating frame is rotatably mounted on the frame body and located between the unwinding assembly and the traction assembly. The rotation axis of the rotating frame is parallel to the rotation direction of the floor fabric roll on the unwinding assembly. There are two limiting rods, which are spaced apart on the rotating frame and located on both sides of the axis of the rotating frame. The floor cloth between the unwinding assembly and the traction assembly passes between the two limiting rods. The rotating frame can level the floor cloth by rotating the two limiting rods by a certain angle.
[0006] As a further technical solution, a pre-leveling component for initially leveling the floor fabric is also included between the rotating frame and the unwinding assembly. The pre-leveling component includes: At least one supporting rotating roller is rotatably mounted on the frame. At least one compression leveling rotary roller is rotatably mounted on the frame, the compression leveling rotary roller being located above or below the support rotary roller, and a passage space for the flooring fabric to pass through is provided between the support rotary roller and the compression leveling rotary roller.
[0007] As a further technical solution, the pre-leveling component also includes: A lifting and adjusting frame is mounted on the frame body, and the extrusion leveling roller is rotatably mounted on the lifting and adjusting frame. The lifting and adjusting frame can adjust the size of the passage space by raising and lowering it.
[0008] As a further technical solution, the traction component includes: A rotating conveyor roller is rotatably mounted on the frame and is connected to a drive device. A conveyor roller lifting frame is mounted on the frame body and can be lowered to approach the rotating conveyor roller. An extrusion conveyor roller is rotatably mounted on the conveyor roller lifting frame, and there is a conveying space between the extrusion conveyor roller and the rotatable conveyor roller for conveying floor cloth.
[0009] As a further technical solution, the extrusion conveyor roller is rotatably and slidably mounted on the conveyor roller lifting frame, and the traction assembly further includes: An elastic element is disposed on the conveyor roller lifting frame, and its two ends act on the conveyor roller lifting frame and the extrusion conveyor roller respectively. The elastic element can provide a force to bring the extrusion conveyor roller closer to the rotating conveyor roller.
[0010] As a further technical solution, the unwinding assembly includes: An air shaft is rotatably mounted on the frame and is used to fix the floor fabric roll. A magnetic powder clutch is disposed between the air shaft and the frame, and the magnetic powder clutch is used to provide rotational damping for the air shaft.
[0011] As a further technical solution, an elbow assembly is also included, which is located between the pre-leveling assembly and the unwinding assembly, and is used to bend the end of the flooring fabric.
[0012] As a further technical solution, the elbow assembly includes: A heating shaft is rotatably mounted on the frame, which has an arc-shaped track, the center of which is located on the axis of the heating shaft. The extrusion roller is slidably disposed within the arc-shaped track. There is a bend between the extrusion roller and the rotating roller for the flooring fabric to pass through. The extrusion roller is able to slide along the arc-shaped track to extrude the end of the flooring fabric to fit against the heating shaft.
[0013] As a further technical solution, the elbow assembly includes: A heating shaft is rotatably mounted on the frame. An arc-shaped extrusion plate is raised and lowered on the frame, and the arc-shaped extrusion plate can be lowered to press the end of the floor cloth to fit against the heating shaft.
[0014] As a further technical solution, two traction components are provided: one traction component is located on the side of the rotating frame away from the unwinding component, and the other traction component is located between the bend component and the pre-leveling component.
[0015] The beneficial effects of this utility model are as follows: In this invention, a rotating frame drives two limiting rollers to rotate, changing the angle between the plane containing the rotation axes of the two rollers and the vertical plane. This causes the flooring fabric to deform in the opposite direction of curling when passing between the two limiting rollers. Furthermore, the rotation of the frame not only allows for leveling of flooring fabrics with different degrees of curl, but also, based on the characteristics of the roll material (the outer ring of the flooring fabric has a lower degree of curl than the inner ring), the angle of the rotating frame can be adjusted in real time according to the position of the flooring fabric on the unwinding assembly.

[0024] like Figures 1-3 The diagram illustrates a flooring roll unwinding mechanism according to an embodiment of the present invention, comprising a frame 100, a rotating frame 410, and limiting rods 420. An unwinding assembly 200 and a traction assembly 300 are rotatably mounted on the frame 100. The unwinding assembly 200 holds the flooring roll, and the traction assembly 300 pulls the flooring roll away from the unwinding assembly 200. The rotating frame 410 is rotatably mounted between the unwinding assembly 200 and the traction assembly 300, with its rotation axis parallel to the rotation direction of the flooring roll on the unwinding assembly 200. Two limiting rods 420 are spaced apart on the rotating frame 410, located on either side of its axis. The flooring roll between the unwinding assembly 200 and the traction assembly 300 passes between these two limiting rods 420. The rotating frame 410 rotates the limiting rods 420 by a certain angle to level the flooring roll. The rotating frame 410 consists of two plate-like structures, which can be elongated or disc-shaped. The two plate-like structures are rotatably mounted on the frame 100 at intervals. The two ends of the limiting rod 420 are rotatably mounted on the two plate-like structures respectively. A rectangular projection is formed between the two limiting rods 420 and the rotating frame 410.
[0025] The rotating frame 410 is connected to a rotation drive device, which drives the rotating frame 410 to rotate. A servo motor is preferred as the rotation drive device. The servo motor allows for precise adjustment of the rotation angle of the rotating frame 410. Initially, the rotation axes of the two limit rods 420 are located in a vertical plane. The flooring fabric passes between the two limit rods 420, which do not perform any leveling function. The rotating frame 410 drives the two limit rods 420 to rotate, causing the plane containing the rotation axes of the two limit rods 420 to rotate 90 to 180 degrees from the initial state, depending on the degree of curl of the flooring fabric. This not only allows for leveling of flooring fabric with different degrees of curl, but also, based on the characteristics of the roll material (the outer ring of the flooring fabric has a lower degree of curl than the inner ring), allows for real-time adjustment of the angle of the rotating frame 410 according to the flooring fabric at different positions on the unwinding assembly 200.
[0026] A pre-leveling assembly 500 is provided between the rotating frame 410 and the unwinding assembly 200. The pre-leveling assembly 500 includes at least one support rotating roller 510 rotatably mounted on the frame 100, and a compression leveling rotating roller 520 also rotatably mounted on the frame 100. The compression leveling rotating roller 520 is located above or below the support rotating roller 510, forming a passage space between them for the flooring fabric to pass through. The flooring fabric is initially leveled by compression through this passage space. Both the support rotating roller 510 and the compression leveling rotating roller 520 are mounted on the frame 100 via bearing seats. Optionally, the two support rotating rollers 510 are rotatably mounted at the same height and horizontally spaced apart. The two support rotating rollers 510 are connected to a drive device via chains, enabling the drive device to rotate both support rotating rollers 510. One compression leveling rotating roller 520 is rotatably mounted above the two support rotating rollers 510, and the axis of rotation of the compression leveling rotating roller 520 is located between the two support rotating rollers 510.
[0027] Furthermore, the pre-leveling assembly 500 is also equipped with a lifting adjustment frame 530, which is lifted and lowered on the frame body 100. The bearing seat of the pressing and leveling rotating roller 520 is rotatably mounted on the lifting adjustment frame 530. The size of the passage space can be adjusted by the lifting adjustment frame 530 to accommodate the leveling requirements of flooring fabrics of different thicknesses. Optionally, the lifting adjustment frame 530 can be driven to lift and lower by a threaded screw, or by a linear drive device such as a cylinder, hydraulic cylinder, or electric cylinder.
[0028] The traction assembly 300 consists of a rotating conveyor roller 310 rotatably mounted on the frame 100 and connected to a drive device, a conveyor roller lifting frame 320 vertically mounted on the frame 100 and lowerable to approach the rotating conveyor roller 310, and a pressing conveyor roller 330 rotatably mounted on the conveyor roller lifting frame 320. There is a conveying space for conveying flooring fabric between the pressing conveyor roller 330 and the rotating conveyor roller 310. The pressing conveyor roller 330 not only rotates but can also slide on the conveyor roller lifting frame 320. The traction assembly 300 is also equipped with an elastic element 340, which is mounted on the conveyor roller lifting frame 320 and acts at both ends on the conveyor roller lifting frame 320 and the pressing conveyor roller 330 respectively, providing a force to the pressing conveyor roller 330 to approach the rotating conveyor roller 310, ensuring that the flooring fabric is stably clamped during conveying.
[0029] The unwinding assembly 200 includes an air shaft 210 rotatably mounted on a frame 100 for securing the flooring roll, and a magnetic powder clutch 220 positioned between the air shaft 210 and the frame 100 to provide rotational damping for the air shaft 210. A corresponding position is pre-drilled on the frame 100, and the air shaft 210 is rotatably connected to the frame 100 via bearings, allowing the air shaft 210 to rotate freely. The flooring roll is fitted onto the air shaft 210, and the air shaft 210 inflates to secure the flooring roll, ensuring that the flooring roll does not slip during unwinding. The magnetic powder clutch 220 is installed between the air shaft 210 and the frame 100, and is connected to the air shaft 210 via a coupling. By controlling the current in the magnetic powder clutch 220, its resistance to the air shaft 210 is changed, thereby controlling the unwinding speed and tension of the flooring roll.
[0030] like Figures 4-5 As shown, a bend assembly 600 is provided between the pre-leveling assembly 500 and the unwinding assembly 200. The bend assembly 600 has two implementation methods. One method consists of a heating shaft 610 rotatably mounted on the frame 100 and a pressing roller 620 slidably mounted in an arc-shaped track 110 on the frame 100. The center of the arc-shaped track 110 is located on the axis of the heating shaft 610. A bend space is formed between the pressing roller 620 and the rotating roller for the flooring fabric to pass through. The pressing roller 620 can slide along the arc-shaped track 110 to press the end of the flooring fabric to fit against the heating shaft 610. When the flooring fabric passes through, the pressing roller 620 slides along the arc-shaped track 110 by external force (such as manual or motor-driven lead screw) to press the end of the flooring fabric to fit against the heating shaft 610, thereby bending the end of the flooring fabric. Another method consists of a heating shaft 610 rotatably mounted on the frame 100 and an arc-shaped extrusion plate 630, which is lowered and positioned on the frame 100 to press the end of the flooring fabric against the heating shaft 610. The arc-shaped extrusion plate 630 can also be raised and lowered using an electric push rod, cylinder, or screw and nut mechanism. When the arc-shaped extrusion plate 630 descends, it presses the end of the flooring fabric against the heating shaft 610, thereby bending the end of the flooring fabric. Both methods can bend the end of the flooring fabric, facilitating subsequent operations.
[0031] The heating shaft 610 has a heating tube inside, which can heat the floor cloth by leveling the end of the floor cloth, making the floor cloth easier to deform.
[0032] Optionally, the device is equipped with two traction components 300, one located on the side of the rotating frame 410 away from the unwinding component 200, and the other located between the bend component 600 and the pre-leveling component 500, to pull the flooring fabric from different positions and better control the unfolding process of the flooring fabric.
[0033] Working principle: The flooring roll is placed on the air shaft 210 of the unwinding assembly 200. The magnetic powder clutch 220 provides rotational damping to control the unwinding speed. After the end of the flooring is bent by the bending assembly 600, the bending assembly 600 releases the flooring. The end of the flooring is manually pulled through the pre-leveling assembly 500, between the two limit rods 420, and the traction assembly 300, and the end of the flooring is fixed on the traction assembly 300. In the pre-leveling assembly 500, the flooring passes through the space between the support rotating roller 510 and the compression leveling rotating roller 520. The lifting adjustment frame 530 can adjust the passage space according to the thickness of the flooring. After the flooring is initially leveled, the flooring passes between the two limit rods 420 on the rotating frame 410. The rotating frame 410 drives the limit rods 420 to rotate a certain angle to further level the flooring. Next, the flooring fabric reaches the traction assembly 300 near the rotating frame 410. The rotating conveyor roller 310 rotates under the drive of the drive device, and the elastic element 340 makes the compression conveyor roller 330 press tightly against the rotating conveyor roller 310, stably clamping and pulling the flooring fabric. At the same time, another traction assembly 300 located between the bend assembly 600 and the pre-leveling assembly 500 works in conjunction to ensure that the flooring fabric is evenly stressed in all parts during the unfolding process, smoothly unfolding from a rolled state to a flat state for subsequent drying.
[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
