Description

Technical Field

[0001] This utility model relates to the field of flexible shaft support technology, and in particular to a flexible shaft support that prevents jamming. Background Art

[0002] Existing glass bending and tempering equipment includes several flexible shaft support seats. The bottom of the flexible shaft support seats is fixedly installed on the side of multiple square tubes facing the glass to be tempered. A spherical bearing is installed in the middle of the support seat. The flexible shaft passes through the spherical bearings in the multiple support seats in sequence and is mounted above the side of multiple square tubes facing the glass to be tempered. The multiple flexible shafts are arranged in parallel along a direction perpendicular to the glass running direction. The bending mechanism is connected to both ends of the multiple square tubes respectively.

[0003] During operation, the bending mechanism drives multiple square tubes to bend and move. The wheel surfaces of multiple transmission wheels mounted on multiple flexible shafts form a curved surface that supports and transports the glass to be tempered. The drive device drives multiple flexible shafts to rotate synchronously and transport the glass to be tempered.

[0004] During operation, the bent flexible shaft forms an arc-shaped curve perpendicular to the direction of glass movement. The middle part of the flexible shaft is located in the middle of the curved surface, and the two ends of the flexible shaft are located on the two straight edges of the curved surface. As the radial depth of the curved surface increases, when the bending angle of the flexible shaft in some parts is too large, the outer circumference of the flexible shaft in these parts will abut against the edge of the hole of the mounting spherical bearing of the support seat, so that the flexible shaft in the corresponding part cannot continue to bend, causing the rotation of the flexible shaft to be obstructed and resulting in jamming, which affects the conveying of the glass to be tempered. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to propose an anti-jamming flexible shaft support seat to solve the problem of jamming caused by obstructed rotation of the flexible shaft.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A type of anti-jamming flexible shaft support includes a connecting seat, a spherical bearing, and two lateral hinge seats;

[0008] The connecting seat has a rotating cavity in the middle; both ends of the connecting seat extend in a direction perpendicular to the axis of the rotating cavity.

[0009] The top of the lateral hinge seat is provided with a rotating cavity; the two lateral hinge seats are rotatably inserted into the two rotating cavities respectively;

[0010] The spherical bearing is rotatably mounted in the rotating cavity and is used to fit onto the outer circumferential surface of the flexible shaft; the bottom of the lateral hinge seat is used to fix to the square tube that drives the flexible shaft to move.

[0011] Furthermore, it also includes two bushings;

[0012] Two bushings are respectively fitted onto both ends of the connecting seat;

[0013] The two ends of the connecting seat are rotatably fitted into the two rotating cavities via corresponding bushings.

[0014] Furthermore, the bushing is provided with a limiting ring;

[0015] The limiting ring surrounds the circumferential edge of the side of the bushing closest to the rotating cavity, and the limiting ring is used to abut against the edge of the corresponding rotating cavity.

[0016] Preferably, the connecting seat comprises two mirror-symmetrical halves, and the rotating cavity is formed by two symmetrically distributed semi-circular grooves joined together.

[0017] Preferably, the bushing is made of polytetrafluoroethylene.

[0018] The beneficial effects of the technical solution of this utility model are as follows: the anti-jamming flexible shaft support seat, with both ends of the connecting seat rotatably embedded in the top of the two lateral hinge seats, allows both ends of the connecting seat to adaptively rotate following the bending of the flexible shaft, which can avoid the bending and rotation of the flexible shaft being obstructed, thereby avoiding jamming.

[0023] The following is in conjunction with the appendix Figure 1-3 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal communication between 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.

[0026] A type of anti-jamming flexible shaft support includes a connecting seat 2, a spherical bearing 3, and two lateral hinge seats 1;

[0027] The connecting seat 2 has a rotating cavity 21 in the middle; both ends of the connecting seat 2 extend in a direction perpendicular to the axis of the rotating cavity 21.

[0028] The top of the lateral hinge seat 1 is provided with a rotating cavity 10; the two lateral hinge seats 1 are rotatably inserted into the two rotating cavities 10 respectively;

[0029] The spherical bearing 3 is rotatably mounted in the rotating cavity 21 and is used to fit onto the outer circumferential surface of the flexible shaft 11; the bottom of the lateral hinge seat 1 is used to fix to the square tube 13 that drives the flexible shaft 11 to move.

[0030] like Figure 1 and Figure 2 The diagram shown is a structural schematic of the anti-jamming flexible shaft support of this utility model.

[0031] Figure 3 This is a schematic diagram of a glass bending mechanism. Multiple square tubes 13 extend along the X-axis. Each square tube 13 has multiple flexible shaft support seats spaced apart along the X-axis on its top surface. Each flexible shaft 11 passes through a spherical bearing 3 in one of the multiple flexible shaft support seats and is mounted above the Z-axis side of the multiple square tubes 13. The multiple flexible shafts 11 are arranged parallel along the Y-axis, and multiple transmission wheels 12 are fitted onto the outer circumference of each flexible shaft 11. The surfaces of the multiple transmission wheels 12 on the multiple flexible shafts 11 form a curved arc surface that supports and transports the glass to be tempered. A drive device can drive the multiple flexible shafts 11 to rotate synchronously, causing the multiple transmission wheels 12 on the multiple flexible shafts 11 to rotate in the X-axis direction and transport the glass to be tempered.

[0032] The anti-jamming flexible shaft support of this utility model has a connection seat 2 whose two ends are rotatably inserted into the rotating cavities 10 of the two lateral hinge seats 1, so that the two ends of the connection seat 2 can adapt to the bending of the flexible shaft 11 and will not jam due to the bending and rotation of the flexible shaft 11.

[0033] Furthermore, it also includes two bushings 4;

[0034] Two bushings 4 are respectively fitted onto both ends of the connecting seat 2;

[0035] The two ends of the connecting seat 2 are rotatably fitted into the two rotating cavities 10 via corresponding bushings 4.

[0036] like Figure 1 and Figure 2 As shown, bushing 4 can reduce the rigid contact and friction between the two ends of connecting seat 2 and rotating cavity 10, and improve the rotational flexibility and service life of the two ends of connecting seat 2.

[0037] Furthermore, the bushing 4 is provided with a limiting ring 41;

[0038] The limiting ring 41 surrounds the circumferential edge of the side of the bushing 4 closest to the rotating cavity 21, and the limiting ring 41 is used to abut against the edge of the corresponding rotating cavity 10.

[0039] like Figure 2 As shown, the limiting ring 41 can improve the installation stability of the bushing 4 and prevent the bushing 4 from loosening by passing through the rotating cavity 10 during operation.

[0040] The connecting seat 2 includes two mirror-symmetrical halves, and the rotating cavity 21 is formed by two semi-circular grooves that are symmetrically distributed vertically.

[0041] like Figure 1 and Figure 2 As shown, dividing the connecting seat 2 into two mirror-symmetrical halves makes it easier to process and shape, and also improves the ease of installation of the spherical bearing 3.

[0042] Preferably, the bushing 4 is made of polytetrafluoroethylene.

[0043] The bushing 4, made of polytetrafluoroethylene, has better wear resistance and service life.

[0044] In summary, such as Figure 1-3 In the embodiment of the present invention shown, the anti-jamming flexible shaft support seat has two ends of the connecting seat 2 rotatably embedded in the top of the two lateral hinge seats 1, so that the two ends of the connecting seat 2 can adaptively rotate with the bending of the flexible shaft 11, which can avoid the bending and rotation of the flexible shaft 11 being obstructed, thereby avoiding jamming.

[0045] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
