Description

Technical Field

[0001] This utility model relates to the technical field of foam production equipment, and in particular, to a tension adaptive winding device for foam production. Background Technology

[0002] Foam is a porous foamed material with low density, soft texture, and high plasticity. It possesses sound absorption and thermal insulation properties and is widely used in construction, medical, and automotive industries. The processing of foam mainly includes steps such as ingredient mixing, melt extrusion, foaming treatment, and cooling. After production, the foam needs to be rolled up for easy storage and transportation. To ensure sufficient tension during winding, a tension roller is typically installed in front of the winding roller. A telescopic rod is mounted on the tension roller's support. By controlling the extension and retraction of the telescopic rod, the position of the tension roller is adjusted, thus regulating the tension. After the tension roller is adjusted, its position remains constant throughout the entire winding process. When the tension of the foam changes during transport, it affects the winding quality. Specifically, when the foam becomes loose, the force exerted by the tension roller decreases, causing the foam to wrap loosely around the winding roller. Conversely, when the foam becomes tight, the force exerted by the tension roller increases, causing the foam to wrap tightly around the winding roller. This inconsistent tension across the winding roller significantly reduces the winding quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is that in the prior art, the tension roller during foam winding cannot be adaptively adjusted, resulting in low winding quality. Based on this, this utility model provides a winding device for foam production with adaptively adjustable tension.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a tension adaptive winding device for foam production, including a base and a guide roller, a tensioning component and a winding roller disposed on the base. The tensioning component is located between the guide roller and the winding roller. The tensioning component includes a fixed seat, a slider, a guide post, an elastic element and a tensioning roller. The fixed seat is fixedly connected to the base. The slider and the guide post are both slidably disposed on the fixed seat along the longitudinal direction. The guide post is located above the slider. The elastic element is connected between the slider and the guide post. The tensioning roller is rotatably mounted on the upper end of the guide post. The fixed seat is provided with a locking element for fixing the slider.

[0005] Furthermore, the upper surface of the fixed base is recessed downward to form a receiving groove, and the bottom wall of the receiving groove is recessed with a sliding groove, and the slider is slidably disposed in the sliding groove along the longitudinal direction.

[0006] Furthermore, a cover plate is fixedly installed on the upper surface of the fixing seat corresponding to the receiving groove, and the lower end of the guide post can slide through the cover plate and extend into the receiving groove.

[0007] Furthermore, the cover plate has a vertical through hole, and the guide post cooperates with the through hole.

[0008] Furthermore, the through hole is a square hole.

[0009] Furthermore, a retaining edge is protruding on the outer wall of the guide post, the retaining edge is located in the receiving groove, the upper end of the elastic element is fixedly connected to the retaining edge, and the lower end of the elastic element is fixedly connected to the slider.

[0010] Furthermore, the locking element is a stud, which is rotatably connected to the bottom of the fixed base in the longitudinal direction, and the stud extends into the slide groove and is threadedly connected to the slider.

[0011] Furthermore, the locking component is a locking bolt, which is horizontally positioned and threaded onto the fixed base. The end of the locking bolt extends into the groove and abuts against the side wall of the slider.

[0012] Furthermore, the tensioning assembly has two components, which are arranged opposite to each other, and a connecting rod is fixedly connected between the guide posts on the two tensioning assemblies.

[0013] The beneficial effects of this utility model are as follows: When the tension of the foam changes during the winding process, the elastic element can automatically extend and retract, thereby causing the tensioning wheel to move automatically upward or downward. This avoids the foam from being overstretched or overly loose, and realizes the function of adaptive tension adjustment of the tensioning wheel. It ensures that the tightness of the foam wound on the winding roller is consistent throughout, thereby improving the winding quality. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] This invention provides a tension-adaptive winding device for foam production, comprising a base 1 and a guide roller 2, a tensioning assembly 3, and a winding roller 4 mounted on the base 1. Both the guide roller 2 and the winding roller 4 are rotatably mounted on the base 1 and are parallel to each other. The tensioning assembly 3 is located between the guide roller 2 and the winding roller 4. During operation, the foam sequentially passes over the guide roller 2 and the tensioning assembly 3 before winding onto the winding roller 4. Figure 2 The direction of the middle arrow indicates the direction of movement of the foam.

[0022] A guide roller bracket 5 and a take-up roller bracket 6 are fixedly mounted on the upper surface of the base 1. The guide roller 2 is rotatably mounted on the upper end of the guide roller bracket 5, and the take-up roller 4 is rotatably mounted on the upper end of the take-up roller bracket 6. Both the guide roller bracket 5 and the take-up roller bracket 6 consist of two vertically arranged and opposite longitudinal plates 51. The two ends of the guide roller 2 and the two ends of the take-up roller 4 are rotatably connected to the longitudinal plates 51 on both sides. To improve the smoothness of rotation, bearings (not shown in the figure) are provided between the guide roller 2 and the take-up roller 4 and the longitudinal plates 51.

[0023] In addition, a winding motor (not shown in the figure) is fixedly installed on one side of the winding roller bracket 6. The output shaft of the winding motor is fixedly connected to one end of the winding roller 4, so that the winding roller 4 can be driven to rotate when the winding motor is started to realize the winding function.

[0024] In this embodiment, the tensioning assembly 3 includes a fixed base 31, a slider 32, a guide post 33, an elastic element 34, and a tensioning roller 35. The fixed base 31 is fixedly connected to the base 1. The slider 32 and the guide post 33 are both slidably disposed on the fixed base 31 along the longitudinal direction. The guide post 33 is located above the slider 32. The elastic element 34 is connected between the slider 32 and the guide post 33. The tensioning roller 35 is parallel to the guide roller 2 and the take-up roller 4 and is rotatably mounted on the upper end of the guide post 33. Foam passes through the bottom of the tensioning roller 35. The fixed base 31 is provided with a locking element 36 for fixing the slider 32.

[0025] During operation, the height of the tension roller 35 is lower than that of the guide roller 2 and the take-up roller 4. When the foam passes through the bottom of the tension roller 35, it exerts an upward thrust on the tension roller 35, causing the elastic element 34 to be stretched. When the tension of the foam increases, its thrust on the tension roller 35 increases, forcing the tension roller 35 to move upward, thus making the foam relatively loose and alleviating the problem of excessive stretching of the foam to some extent. Conversely, when the tension of the foam decreases, its thrust on the tension roller 35 decreases, and under the elastic force of the elastic element 34, the tension roller 35 moves downward, thus making the foam relatively tight and alleviating the problem of excessive looseness of the foam to some extent. In this way, the tension roller 35 achieves the function of adaptive tension adjustment, ensuring that the tightness of the foam wound on the take-up roller 4 is consistent throughout, thereby improving the take-up quality.

[0026] Before starting the winding operation, the connection position at the bottom of the elastic element 34 is adjusted by moving the slider 32, thereby adjusting the squeezing force of the tension roller 35 on the foam. After the adjustment is completed, the slider 32 can be locked and fixed on the fixed seat 31 by the locking element 36.

[0027] In a preferred embodiment, the upper surface of the fixing base 31 is recessed downward to form a receiving groove 311. A sliding groove 312 is recessed in the bottom wall of the receiving groove 311, and the slider 32 is slidably disposed within the sliding groove 312 along the longitudinal direction. A cover plate 313 is fixedly installed on the upper surface of the fixing base 31 corresponding to the receiving groove 311. The lower end of the guide post 33 slidably passes through the cover plate 313 and extends into the receiving groove 311. Specifically, a through hole 314 is vertically formed on the cover plate 313. The guide post 33 cooperates with the through hole 314, and the through hole 314 guides the guide post 33, ensuring that the guide post 33 can only move longitudinally. Furthermore, the through hole 314 is a square hole, preventing the guide post 33 from rotating when it is engaged with the square hole, ensuring that the guide post 33 can only move longitudinally. Additionally, the cover plate 313 is fixedly connected to the upper surface of the fixing base 31 by fixing bolts 315.

[0028] A retaining flange 331 protrudes from the outer wall of the guide post 33. The retaining flange 331 is located within the receiving groove 311. The upper end of the elastic element 34 is fixedly connected to the retaining flange 331, and the lower end of the elastic element 34 is fixedly connected to the slider 32. Under normal operation, the retaining flange 331 moves up and down within the receiving groove 311 as the tension of the foam changes. In extreme cases, such as when the winding motor 61 rotates at high speed due to malfunction, the retaining flange 331 will move upward and abut against the cover plate 313. In this case, the guide post 33 is prevented from detaching from the fixed seat 31, and the elastic element 34 is also prevented from being damaged due to excessive stretching. As a preferred embodiment, the elastic element 34 is a spring.

[0029] In this embodiment, the locking element 36 is a stud. Specifically, the stud is rotatably connected to the bottom of the fixed base 31 along the longitudinal direction. The stud extends into the slide groove 312 and is threadedly connected to the slider 32. During operation, rotating the stud drives the slider 32 to move up or down within the slide groove 312. Since the stud itself has a self-locking function, when the stud stops rotating, the slider 32 is naturally locked onto the fixed base 31. The rotation of the stud can be done manually or by a motor; this is not limited here. Furthermore, to facilitate the rotation of the stud, multiple support plates 37 are fixedly connected to the lower surface of the fixed base 31. The lower end of the support plates 37 is fixedly connected to the base 1. By setting the support plates 37, the fixed base 31 is supported, ensuring that the bottom of the fixed base 31 has space for operating the stud, thereby facilitating user operation.

[0030] In other embodiments not shown, the locking element 36 is a locking bolt, which is horizontally positioned and threaded onto the fixing seat 31. The end of the locking bolt extends into the sliding groove 312 and abuts against the side wall of the slider 32. In use, after the slider 32 has moved to its designated position, the user can lock and fix the slider 32 onto the fixing seat 31 by tightening the locking bolt. The specific structure of the locking element 36 and the method of locking and fixing the slider 32 are not specifically limited here.

[0031] In addition, there are two tensioning components 3, which are arranged opposite to each other. A connecting rod 38 is fixedly connected between the guide posts 33 on the two tensioning components 3 to ensure that the guide posts 33 on both sides can move synchronously, thereby improving the movement stability of the tensioning roller 35.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
