Description

Technical Field

[0001] This utility model relates to a mechanical servo feeder. Background Technology

[0002] The strip material punched by the punch press is usually conveyed by a feeder. Existing feeders, such as the CNC strip feeding machine with integrated pneumatic and mechanical release disclosed in Chinese Invention Patent Specification CN103043480 B, include a frame, an upper roller seat, an upper roller, a lower roller, a mechanical release rotating shaft, a strike rod, and a return spring. The upper roller is rotatably mounted in the upper roller seat, and the lower roller and the rotating shaft are rotatably mounted in the frame. The strike rod is fixedly mounted on the rotating shaft. The upper roller seat is oscillatingly mounted in the frame between a pressing position where the upper roller is close to the lower roller and an lifting position where the upper roller is away from the lower roller. The upper roller seat has a support arm extending toward the rotating shaft. The return spring is located between the upper roller seat and the frame, and the return spring drives the upper roller seat back to the pressing position. In existing methods, to enable the upper roller seat to swing upwards via a mechanically loosening rotating shaft, a tangential surface is typically provided on the rotating shaft. The support arm of the upper roller seat rests on this tangential surface. When the rotating shaft rotates, the edge of the tangential surface prys up the upper roller seat, causing it to swing upwards from a depressed position to an elevated position, thereby releasing the material strip clamped by the upper and lower rollers. This method of prying using the edge of the tangential surface results in significant wear and requires frequent replacement of the mechanically loosening rotating shaft, increasing production costs and impacting production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a mechanical servo feeder, including a frame, an upper roller seat, an upper roller, a lower roller, a rotating shaft, a strike rod, and a return spring. The upper roller is rotatably mounted in the upper roller seat, and the lower roller and the rotating shaft are rotatably mounted in the frame. The strike rod is fixedly mounted on the rotating shaft. The upper roller seat is oscillatingly mounted in the frame between a downward pressing position that brings the upper roller closer to the lower roller and an upward lifting position that moves the upper roller away from the lower roller. The upper roller seat is provided with a support arm extending toward the rotating shaft. A return spring is located between the upper roller seat and the frame, and the return spring drives the upper roller seat back to the pressed position. A support assembly is provided on the rotating shaft. The support assembly includes a wheel frame and a support roller. The wheel frame is fixedly mounted on the rotating shaft and has an outer end extending toward the upper roller seat and protruding beyond the rotating shaft. The support roller is rotatably mounted on the outer end of the wheel frame. The support arm of the upper roller seat rests on the support roller. When the rotating shaft rotates, the support roller pries up the upper roller seat so that the upper roller seat swings from the pressed position to the raised position.

[0004] This invention uses support rollers to pry the upper roller seat, which can effectively reduce wear, reduce the number of downtimes for replacing parts, and improve production efficiency. At the same time, even if wear occurs, only the support rollers need to be replaced, without replacing the rotating shaft, thereby reducing production costs. Attached Figure Description

[0014] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0015] like Figures 1 to 3The mechanical servo feeder shown includes a frame 10, an upper roller seat 20, an upper roller 30, a lower roller 40, a rotating shaft 50, a strike rod 60, and a return spring (not shown). The upper roller 30 is rotatably mounted in the upper roller seat 20. The lower roller 40 and the rotating shaft 50 are both rotatably mounted in the frame 10. The strike rod 60 is fixedly mounted on the rotating shaft 50. The upper roller seat 20 is positioned such that the upper roller 30 is close to the lower roller. The upper roller 30 is oscillatingly mounted in the frame 10 between a downward pressing position and an upward lifting position that moves the lower roller 40 away from the lower roller 40. The upper roller seat 20 is provided with a support arm 201 extending toward the rotation axis 50. The return spring is provided between the upper roller seat 20 and the frame 10. The return spring drives the upper roller seat 20 back to the downward pressing position. The return spring of this utility model can be set using existing technology. For example, see the return spring in a CNC tape feeder with integrated pneumatic and mechanical release disclosed in Chinese Invention Patent Specification CN103043480 B.

[0016] A support assembly is provided on the rotating shaft 50. The support assembly includes a wheel frame 70 and a support roller 80. The wheel frame 70 is fixedly mounted on the rotating shaft 50. The wheel frame 70 has an outer end 701 extending toward the upper roller seat 20 and protruding beyond the rotating shaft 50. The support roller 80 is rotatably mounted on the outer end 701 of the wheel frame. The support arm 201 of the upper roller seat rests on the support roller 80. When the rotating shaft 50 rotates, the support roller 801 pries up the upper roller seat 20 so that the upper roller seat 20 swings from a pressed position to an raised position.

[0017] This technical solution uses support rollers to pry the upper roller seat, replacing the original sliding friction with rolling friction, which can effectively reduce wear, reduce the number of downtimes to replace parts, and improve production efficiency. At the same time, even if wear occurs, only the support rollers need to be replaced, without replacing the rotating shaft, thereby reducing production costs.

[0018] The rotating shaft 50 is provided with a cutting plane 501, and the wheel frame 70 is fixedly installed on the cutting plane 501. This design facilitates the installation of the wheel frame. In this embodiment, the wheel frame can be installed by screws 702.

[0019] The upper roller seat has two support arms 201, which are located on opposite sides of the upper roller seat 20. Each support arm 201 is equipped with a set of support components on the rotating shaft 50. This technical solution improves the stability and reliability of prying the upper roller seat.

[0020] Structures not specifically described in this utility model can be achieved using existing technologies, such as the mechanical servo feeder disclosed in Chinese Utility Model Patent Specification CN 214442540 U.

[0021] The levering principle of this utility model can be found below.

[0022] like Figure 6 As shown, the upper roller seat 20 is in the pressed-down position, the support arm 201 of the upper roller seat rests on the support roller 80, the upper roller 30 is close to the lower roller 40, and the rolled material strip 100 is clamped between the upper roller 30 and the lower roller 40.

[0023] exist Figure 6 Based on this, the downward-pressing rod 60 drives the rotating shaft 50 along... Figure 6 When rotated clockwise, the wheel frame 70 and its supporting rollers 80 will rotate with the rotating shaft 50, causing the supporting rollers 80 to pry the upper roller seat 20 to swing upward.

[0024] like Figure 7 As described above, the upper roller seat 20 swings upward to the raised position, at which time the upper roller 30 moves away from the lower roller 40, and the rolled material belt 100 is loosened.

[0025] Subsequently, when the downward pressure applied to the strike lever 60 is removed, the upper roller seat 20 swings down from the raised position to the pressed position under the action of the return spring, and at the same time, the support arm 201 also presses down to support the roller 80, so that the rotating shaft 50 returns to its original position.
