Description

Technical Field

[0001] This utility model belongs to the field of material receiving devices, specifically relating to a material receiving mechanism that can adjust the material receiving tension. Background Technology

[0002] Currently, the industry's wire take-up devices for insulating sleeves and similar products generally include a take-up roller and a displacement controller that reciprocates along the axial direction of the take-up roller. The wire is wound onto the take-up roller after passing through the displacement controller, and the wire is arranged along the axial direction of the take-up roller under the movement of the displacement controller.

[0003] However, in actual production, as the position of the wire changes on the take-up roller, the surface tension of the wire cannot remain stable. This can easily lead to the wire becoming too loose or too tight, resulting in problems such as loose wire arrangement or deformation and breakage. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a brand-new material receiving mechanism that can adjust the material receiving tension.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A take-up mechanism capable of adjusting take-up tension includes a take-up roller and a displacement component. The take-up mechanism also includes a tension adjustment component, which includes a base, a turning frame pivotally connected to the base, and a driver. The pivot is arranged parallel to the take-up roller, and the displacement component and the take-up roller are sequentially arranged on the turning frame along the take-up direction. As the displacement component drives the wire to reciprocate along the axial direction of the take-up roller, the driver synchronously drives the turning frame to reciprocate around the pivot centerline. The wire is wound around the take-up roller with constant tension and arranged along the axial direction of the take-up roller.

[0007] According to a specific embodiment and preferred aspect of this utility model, the wire is defined as having a transmission section and a take-up section located between the displacement component and the take-up roller in the take-up direction. As the angle between the projections of the take-up section and the transmission section on the horizontal plane increases or decreases, the angle at which the drive unit drives the turning frame to rotate around the pivot centerline gradually increases or decreases. Here, as the angle between the projections of the take-up section and the transmission section on the horizontal plane increases, the surface tension of the wire decreases, requiring the turning frame to rotate at a larger angle and pull on the wire to increase the surface tension. Conversely, as the angle between the projections of the take-up section and the transmission section on the horizontal plane decreases, the surface tension of the wire increases, requiring the turning frame to rotate at a smaller angle and relax the wire to avoid excessive surface tension and deformation, thus achieving a dynamic balance of tension.

[0008] Preferably, when the take-up section is located at one end of the take-up roller, the projections of the transmission section and the take-up section on the horizontal plane form a flat angle. This facilitates the gradual and close arrangement of the wires from one end of the take-up roller to the other.

[0009] According to another specific embodiment and preferred aspect of this utility model, the tilting frame includes a first frame and a second frame extending radially along a pivot, wherein the receiving roller is rotatably connected to the first frame, and the displacement component is disposed on the second frame. Here, the structure is simple and easy to install and implement.

[0010] Preferably, in the orthographic projection along the pivot axis, the included angle between the first frame and the second frame is 80° to 100°. In some specific embodiments, the included angle between the first frame and the second frame is 90°.

[0011] According to another specific embodiment and preferred aspect of this utility model, the displacement component includes a power screw mounted on a second frame and extending axially along a pivot, a displacement module threadedly matched with the power screw, and a guide wheel mounted on the displacement module. Here, precise control of the wire's axial displacement on the take-up roller is achieved to improve winding and arrangement accuracy.

[0012] Preferably, the displacement component further includes a guide rod disposed on the second frame and extending axially along the pivot, and a first extension sleeved on the guide rod is formed on the displacement module. This improves displacement stability.

[0013] Preferably, the displacement component further includes a limiting rod disposed on the second frame and extending axially along the pivot, two limiting blocks spaced apart on the limiting rod and aligned with both ends of the receiving roller, and a second extension portion formed on the displacement module between the two limiting blocks.

[0014] Preferably, the take-up mechanism further includes a power motor that drives the take-up roller to rotate around its own center line, and a synchronous belt is connected between the output shaft of the power motor and the power lead screw. This ensures that the winding and displacement of the wire are synchronized or stopped.

[0015] In addition, the actuator includes a telescopic rod, the two ends of which are rotatably connected to the base and the first frame, respectively.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] In existing technologies, as the position of the wire changes on the take-up roller, the surface tension of the wire cannot remain stable, easily leading to insufficient or excessive tension, causing the wire to become loose or overly taut, resulting in problems such as loose wire arrangement or deformation and breakage. This application addresses the shortcomings and defects of existing technologies by comprehensively designing the structure of the take-up mechanism that can adjust the take-up tension. With this take-up mechanism, when the wire is transferred from the previous processing station to the take-up mechanism, the displacement component controls the wire to reciprocate along the axial direction of the take-up roller, and the driver drives the flipping frame to reciprocate around the pivot center line to adjust the position of the displacement component and the take-up roller, thereby adjusting the surface tension of the wire in real time, so that the wire is wound around the take-up roller with constant tension and arranged sequentially along the axial direction of the take-up roller. Therefore, compared with the prior art, this utility model, on the one hand, adjusts the position of the displacement component and the take-up roller based on the flipping motion of the flipping frame, and adjusts the surface of the wire in real time to achieve constant tension winding and tight arrangement of the wire, effectively improving the winding quality and reducing the probability of wire deformation and breakage; on the other hand, it has a simple structure, is easy to implement and has low cost.

[0032] like Figures 1 to 4 As shown, the material receiving mechanism capable of adjusting the receiving tension involved in this embodiment includes a receiving roller 1, a displacement component 2, and a tension adjusting component 3.

[0033] Specifically, the take-up roller 1 is a conventional take-up roller; the displacement component 2 is used to drive the wire X to reciprocate along the axial direction of the take-up roller 1, and includes a power screw 20, a displacement module 21 threadedly matched with the power screw 20, and a guide wheel 22 disposed on the displacement module 21; the tension adjustment component 3 includes a base 30, a flipping frame 31 rotatably connected to the base 30 via a pivot s, and a driver 32, wherein the pivot s is arranged parallel to the take-up roller 1, and the displacement component 2 and the take-up roller 1 are sequentially disposed on the flipping frame 31 along the take-up direction. As the displacement component 3 drives the wire X to reciprocate along the axial direction of the take-up roller 1, the driver 32 synchronously drives the flipping frame 31 to reciprocate around the center line of the pivot s. The wire X is wound around the take-up roller 1 with constant tension and arranged along the axial direction of the take-up roller 1.

[0034] Simultaneously, the wire X is defined in the take-up direction as a transmission segment X1 (located between the preceding processing station and the displacement component 2) and a take-up segment X2 located between the displacement component 2 and the take-up roller 1. As the angle between the projections of the take-up segment X2 and the transmission segment X1 on the horizontal plane increases or decreases, the driver 32 drives the flipping frame 31 to gradually increase or decrease the angle of rotation around the pivot s centerline. Here, as the angle between the projections of the take-up segment and the transmission segment on the horizontal plane increases, the surface tension of the wire decreases, requiring the flipping frame to increase the rotation angle and pull on the wire to improve the surface tension. Conversely, as the angle between the projections of the take-up segment and the transmission segment on the horizontal plane decreases, the surface tension of the wire increases, requiring the flipping frame to decrease the rotation angle and relax the wire to avoid excessive surface tension and deformation, thus achieving dynamic tension balance. In some specific embodiments, when the take-up segment X2 is located at one end of the take-up roller 1, the projections of the transmission segment X1 and the take-up segment X2 on the horizontal plane form a flat angle, so that the wires can be gradually and closely arranged from one end of the take-up roller to the other end.

[0035] In this example, the power screw 20 extends axially along the pivot; the displacement component 2 also includes a guide rod 23 extending axially along the pivot s, and a first extension b1 is formed on the displacement module 21 and sleeved on the guide rod 23; the displacement component 2 also includes a limiting rod 24 extending axially along the pivot s and located below the displacement module 21, and two limiting blocks 25 spaced apart on the limiting rod 24 and aligned with both ends of the receiving roller 1, and a second extension b2 is formed on the displacement module 21 located between the two limiting blocks 25.

[0036] For ease of implementation, the take-up mechanism also includes a power motor 4 that drives the take-up roller 1 to rotate around its own center line. A synchronous belt (not shown in the figure, but easy to imagine) connects the output shaft of the power motor 4 to the power lead screw 20. Here, it is ensured that the winding and displacement are synchronized or stopped.

[0037] In this example, the flipping frame 31 includes a first frame 311 and a second frame 312 that extend radially along the pivot s, respectively. The receiving roller 1 is rotatably connected to the first frame 311, and the displacement component 2 is disposed on the second frame 312. That is, the power screw 20, the guide rod 23, and the limiting rod 24 are respectively arranged on the second frame 312.

[0038] Meanwhile, in the orthographic projection along the pivot s-axis, the included angle between the first frame 311 and the second frame 312 is 80° to 100°. In some specific embodiments, the included angle between the first frame and the second frame is 90°.

[0039] In addition, the driver 32 includes a telescopic rod 320, the two ends of which are rotatably connected to the base 30 and the first frame 311, respectively. One or two telescopic rods 320 can be provided.

[0040] In summary, with this take-up mechanism, when the wire is transferred from the previous processing station to the take-up mechanism, the displacement component controls the wire to reciprocate along the axial direction of the take-up roller, and the driver drives the flipping frame to reciprocate around the pivot center line to adjust the position of the displacement component and the take-up roller, thereby adjusting the surface tension of the wire in real time, so that the wire is wound around the take-up roller with constant tension and arranged sequentially along the axial direction of the take-up roller. Therefore, compared with the prior art, this utility model has several advantages. First, it adjusts the position of the displacement component and the take-up roller based on the flipping motion of the flipping frame, thereby adjusting the wire surface in real time. This allows the wire to maintain constant tension during winding and to be tightly arranged, effectively improving winding quality and reducing the probability of wire deformation and breakage. Second, it has a simple structure, is easy to implement, and has low cost. Third, as the angle between the projections of the take-up section and the transmission section on the horizontal plane increases, the surface tension of the wire decreases, requiring the flipping frame to increase its flipping angle and pull on the wire to increase its surface tension. Conversely, as the angle between the projections of the take-up section and the transmission section on the horizontal plane decreases, the surface tension of the wire increases, requiring the flipping frame to decrease its flipping angle and loosen the wire to avoid excessive surface tension and deformation, thus achieving dynamic tension balance. Fourth, it ensures that winding and displacement are carried out or stopped synchronously.

[0041] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
