AI Technical Summary

Technical Problem

In existing technologies, the number of stacked papers is determined by measuring the lifting and lowering displacement of the pressure rollers. This requires the use of high-resolution sensors and supporting equipment, resulting in high manufacturing and maintenance costs, which limits market competitiveness and widespread adoption.

Method used

By adopting a paper-pressing roller design, the lifting displacement of the paper-pressing roller is converted into the swing angle detection of the swing component, and the angle change is amplified into linear displacement output through the lever principle, replacing the high-resolution sensor and reducing the dependence on high-precision sensors.

Benefits of technology

This reduces the overall manufacturing and maintenance costs of the machine, improves the accuracy of paper quantity determination, and enhances market competitiveness.

Abstract

本申请提供了一种压纸轮,包括转轮、固定件、摆动件和测距构件;摆动件铰接在固定件上;转轮转动设置在摆动件上,且与摆动件的铰接轴非同轴设置,以使其具有环绕摆动件铰接轴的旋转自由度;摆动件上具有延长臂,测距构件测量端朝向该延长臂,且测量端朝向与摆动件铰接轴垂直,以形成位于延长臂表面的测距点。当摆动件摆动时,该测距点沿延长臂的长度方向移动;由于测距点与摆动件铰接轴的间距大于摆动件铰接轴与转轮转动轴的间距,因此根据杠杆原理,转轮的移动数据被放大,通过测距构件的读数可以更为直观、清楚的判定转轮下方的纸张数量。本申请提供的压纸轮,能够降低对传感器分辨率的要求,免除对高分辨率传感器及其配套设备的依赖。

Claims

1. A paper pressing wheel comprising a rotating wheel for rotating a paper stack area provided with a paper feeding belt for pressing the stacked paper; characterized in that, The paper pressing roller also includes: Fasteners are used to secure the paper stacking area; A swing member is hinged to the fixed member; the rotating wheel is rotatably connected to the swing member, and its rotational axis is parallel to the hinge axis of the swing member, forming a rotational degree of freedom around the rotation axis of the swing member; the swing member has an extension arm extending upward in a direction perpendicular to its hinge axis; and A ranging component is fixed above the swing member, with its measuring end facing the extension arm and the orientation of the measuring end perpendicular to the hinge axis of the swing member, to form a ranging point located on the surface of the extension arm; when the swing member swings, the ranging point moves along the length direction of the extension arm; The ranging component is used to monitor the distance between the measuring end and the ranging point, and the distance between the ranging point and the hinge axis of the swing component is greater than the distance between the hinge axis of the swing component and the rotation axis of the wheel.

2. The platen as recited in claim 1, wherein The swing element includes: The connecting part is hinged to the fixing member; and Both mounting parts are located on the outer wall of the connecting part; The mounting portion extends outward in a direction perpendicular to the hinge axis of the connecting portion, and the extension arm and the rotating wheel are respectively disposed on the two mounting portions.

3. The platen as recited in claim 2, wherein, In the extending direction of the mounting portion connected to the extension arm, the extension arm is inclined away from the ranging member.

4. The press wheel of claim 2 or 3, wherein A limiting arm is fixedly provided on the fixing member. Part of the limiting arm and the fixing member are located on both sides of the extension arm, and the limiting arm is used to abut against the extension arm to restrict the wheel from moving downward around the rotation axis of the swing member.

5. The press wheel of claim 2 or 3, wherein The lower end of the fastener has a groove; the connecting part is hinged to the inner wall of the groove, and one of the mounting parts is located inside the groove, while the extension arm is located outside the groove.

6. The platen as recited in claim 1, wherein The fixing member is provided with an elastic reset member; the elastic reset member is connected to the swing member and is used to drive the swing member to swing, so that the rotating wheel moves downward around the rotation axis of the swing member to press the stacked paper.

7. The platen as recited in claim 6, wherein The elastic reset element includes: A positioning shaft is fixedly disposed on the outside of the fixing member, and its axial direction is parallel to the hinge axis of the swing member; and A torsion spring is sleeved on the positioning shaft, with one end connected to the positioning shaft and the other end connected to the swing member.

8. The platen as recited in claim 1, wherein The paper pressing roller also includes: A crossbeam, used to fix the paper stacking area, has its length parallel to the horizontal plane and perpendicular to the direction of paper entry and exit; and The mounting component is slidably disposed on the crossbeam along the length direction of the crossbeam and has a locking structure with the crossbeam; The locking structure is used to connect the mounting member and the crossbeam to restrict the movement of the mounting member relative to the crossbeam; and the fixing member is detachably connected to the mounting member.

9. The platen as recited in claim 8, wherein, The outer side of the mounting component has a reserved groove running through the vertical direction, and a sealing plate that is detachably connected thereto. The sealing plate and the reserved groove form a through-cavity in the vertical direction. The fastener is inserted into the mounting cavity and is interference-fitted with the mounting cavity.

10. The platen as recited in claim 8, wherein, The mounting component has a sliding groove that extends along the sliding direction of the mounting component, and the crossbeam is embedded in the sliding groove; The locking structure includes: A threaded hole is formed on the mounting component and communicates with the sliding groove; and A positioning bolt is threaded into the threaded hole to be suitable for extending into the groove and abutting against the crossbeam; The threaded hole is arranged axially and non-parallel to the orientation of the slide groove, so that when the positioning bolt abuts against the crossbeam, it can prevent the crossbeam from disengaging from the slide groove.
