Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a wire feeding mechanism for a wire stripper. Background Technology

[0002] Existing patent (CN216015971U) discloses an automatic wire feeding, stripping, and output mechanism and an automatic terminal block machine, including a wire feeding device 30. (This is in conjunction with its patent appendix.) Figure 1 It can be seen that the wire feeding device 30 has several rollers that alternate up and down, which are used to clamp and guide the wire. However, it only clamps the wire from top to bottom, and the clamping effect needs to be improved. Utility Model Content

[0003] This utility model provides a wire feeding mechanism for a wire stripper to solve the technical problem of poor wire feeding effect caused by the clamping restriction direction being limited to only up and down.

[0004] The present invention solves the above-mentioned technical problems by adopting the following technical solution: A wire feeding mechanism for a wire stripping machine, comprising: A feed spool that runs from front to back; The mounting bracket is fixed to the wire feed drum and secured to the wire stripper with bolts; An adjusting disc is located in the middle of the wire feeding drum. The adjusting disc is provided with main push arms distributed at equal angles around its circumference. The main push arms can move radially relative to the adjusting disc. Auxiliary rods are slidably disposed at both ends of the wire feeding drum at equal angles in the circumference. The axis of the auxiliary rods is perpendicular to the axis of the wire feeding drum. The number and circumferential installation position of the auxiliary rods at each end correspond to the main push arm. The wire clamping wheel frame is fixed to the inner end of the auxiliary rod and the main push arm, and the wire clamping wheel frame is provided with wire clamping wheels at intervals.

[0005] Preferably, the regulating plate has four main push arms arranged in a circular array, and the regulating plate also has a transmission part that mechanically connects adjacent main push arms. When one main push arm moves relative to the wire feeding drum, the other main push arms move synchronously in the same direction.

[0006] Preferably, the transmission unit includes a synchronous transmission gear and a bearing that matches the synchronous transmission gear. The rotation axis of the synchronous transmission gear is parallel to the axis of the wire feed drum, and the side wall of the main push arm is provided with straight teeth. The synchronous transmission gear meshes with the straight teeth on the side wall of the main push arm. When one of the main push arms moves, the power is transmitted synchronously through the meshing of the straight teeth and the synchronous transmission gear.

[0007] Preferably, the number of synchronous transmission gears between two adjacent main push arms is even.

[0008] Preferably, it further includes an adjustment unit, which includes an adjustment frame, a manual handle, and a screw. The shaft end of the screw is coaxially fixed with the manual handle, and the screw is rotatably mounted on the adjustment frame. The adjustment frame is fixed to the outer wall of the adjustment disc. One of the main push arms is provided with a screw hole perpendicular to the axis of the wire feed drum. The screw is threadedly connected to the screw hole. Rotating the manual handle causes the main push arm to move radially relative to the adjustment disc through the engagement of the helical pair.

[0009] Preferably, the main push arm sidewall is provided with a sliding guide protrusion, the inner wall of the adjustment disk is provided with a guide groove, and the sliding guide protrusion is fitted and slidably disposed in the guide groove.

[0010] Preferably, the wire feeder is provided with viewing windows at an annular interval.

[0011] The beneficial effects of this utility model are: the wire can be rolled and clamped in four directions (up, down, left, and right) by the clamping wheels, and the wire can be smoothly passed through the device by the rolling of the clamping wheels. Compared with the prior art, the clamping effect is better in the up and down direction only. Attached Figure Description

[0015] The present invention will now be described in further 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. The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings: like Figure 1-4As shown, the wire feeding mechanism of the wire stripper described in this utility model includes: 12-tube wire feeder, running through both ends; Mounting bracket 11 is fixed to wire feeding drum 12 and bolted to wire stripper; An adjusting disc 14 is disposed in the middle of the wire feeding drum 12. The adjusting disc 14 is provided with main push arms 19 distributed at equal angles around the circumference. The main push arms 19 can move radially relative to the adjusting disc 14. Auxiliary rods 13 are circumferentially and angularly slidably disposed at both ends of the wire feed cylinder 12 (e.g., Figure 1 The axis of the auxiliary rod 13 is perpendicular to the axis of the wire feeding drum 12, and the number and circumferential installation position of the auxiliary rod 13 at each end correspond to the main push arm 19; The wire clamping wheel frame 22 is fixed to the inner end of the auxiliary rod 13 and the main push arm 19, and the wire clamping wheel frame 22 is provided with wire clamping wheels 21 at intervals. Specifically, the wire clamping wheels 21 are arranged in a ring-shaped interval in the circumferential direction and are arranged at intervals in the axial direction to clamp the wire 10 in the designated path. Since the wire clamping wheels 21 can rotate, the wire 10 can move smoothly relative to the axis of the wire feeding drum 12 and maintain a good straight shape, which is convenient for subsequent processing.

[0016] Preferably, the adjusting disk 14 has four main push arms 19 arranged in a circular array. The adjusting disk 14 also has a transmission part 24, which mechanically connects adjacent main push arms 19. When one main push arm 19 moves relative to the wire feeding drum 12, the other main push arms 19 move synchronously in the same direction. This makes it more convenient to adjust the distance between the clamping wheel 21 and the axis of the wire feeding drum 12 and ensures that the adjustment distance is the same.

[0017] Preferably, the transmission unit 24 includes a synchronous transmission gear 20 and a bearing that matches the synchronous transmission gear 20. The rotation axis of the synchronous transmission gear 20 is parallel to the axis of the wire feed drum 12, and the side wall of the main push arm 19 is provided with straight teeth. The synchronous transmission gear 20 meshes with the straight teeth on the side wall of the main push arm 19 (e.g., ...). Figure 4 When one of the main push arms 19 moves, it transmits power synchronously through the meshing of the spur gear and the synchronous transmission gear 20.

[0018] Preferably, the number of synchronous transmission gears 20 between two adjacent main push arms 19 is even. This ensures that the main push arms 19 move in the same direction. Furthermore, to reduce cost and weight, the synchronous transmission gears 20 may not be provided between two adjacent main push arms 19. Figure 4 .

[0019] Preferably, it also includes an adjustment unit 15, which includes an adjustment frame 16, a manual handle 17, and a screw 18. The shaft end of the screw 18 is coaxially fixed with the manual handle 17, and the screw 18 is rotatably mounted on the adjustment frame 16. The adjustment frame 16 is fixed to the outer wall of the adjustment disc 14. One of the main push arms 19 is provided with a screw hole perpendicular to the axis of the wire feeding drum 12. The screw 18 is threadedly connected to the screw hole. By rotating the manual handle 17, the main push arm 19 moves radially relative to the adjustment disc 14 through the movement of the screw pair, thereby adjusting the position of the wire clamping wheel frame 22. After the position of the wire clamping wheel frame 22 is changed, it can clamp and feed wires 10 of different diameters within a specified range.

[0020] Preferably, the main push arm 19 has a sliding guide protrusion 25 on its side wall, and the adjusting disk 14 has a guide groove 26 on its inner wall. The sliding guide protrusion 25 is fitted and slidably disposed within the guide groove 26. Specifically, the sliding guide protrusion 25 can be of other shapes, such as a dovetail groove, and the corresponding guide groove 26 can be a dovetail groove. Figure 3 In the embodiments, T-shaped sliders are used to match T-shaped slots.

[0021] Preferably, the wire feed drum 12 is provided with viewing windows 23 at intervals in a ring to facilitate observation of the operation of the wire clamping wheel 21 and its clamping of the wire 10, such as... Figure 4 .

[0022] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
