Description

Technical Field

[0001] This utility model relates to the technical field of electrical control components for textile machinery, and in particular to an optocoupler switch button assembly for starting and stopping a single spindle of a spinning machine. Background Technology

[0002] Spinnerets on spinning machines typically require start-stop control of individual spindles during operation such as stopping, splicing, and roving. Existing single-spindle control buttons mostly use mechanical contact switches or simple photoelectric shielding switches, which have the following shortcomings: First, the buttons, bases, and status indicator lights are scattered or not intuitively displayed, making it inconvenient to identify the open / closed status on-site; second, the button assembly locking structure is inadequate, making them prone to loosening under long-term vibration and frequent pressing; third, springs and other reset components are exposed or poorly protected, easily accumulating dust; and fourth, replacing the light-shielding parts is inconvenient, resulting in low maintenance efficiency.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an optocoupler switch button assembly.

[0005] To achieve the above objectives, this utility model provides an optocoupler switch button assembly for use in the spindle box mounted on the ring rail of a spinning machine to control a single spindle, comprising: a button, a base, a light shield, and a reset spring disposed within the base; The button is mounted on the base. The button can move back and forth relative to the base in the pressing direction. One end of the return spring abuts against the button and the other end abuts against the base. The button has multiple split pins extending in the pressing direction on the side facing the base. Each split pin includes at least two pins with barbs at the ends. The light shield is disposed between the multiple split pins and is linked to the button, such that when the button is pressed, the light shield extends outward relative to the base to block the light path of the optocoupler sensor, and when the button is released, it retracts under the action of the reset spring to release the blockage. The barbs of the barbed prongs engage with the base to lock the button to the base. Multiple separate prongs, under the pressure of the base, use their own elasticity to hold the light shield to prevent it from falling. The base is positioned close to the open / closed status indicator light on the control panel. The base is made of a light-transmitting material, so that the brightness changes of the open / closed status indicator light are presented through the base to indicate the open / closed status of the button.

[0006] The number of split pins is four, of which two are barbed pins arranged opposite each other, and the other two are barbed pins arranged opposite each other.

[0007] The base is hollow, forming a first through hole and a second through hole that are connected. A first step is formed at the connection between the first through hole and the second through hole. The button includes a keycap and a light-shielding plate mounting part connected to the keycap. The reset spring is sleeved on the light-shielding plate mounting part. The outer diameter of the keycap matches the diameter of the first through hole, and the bottom of the keycap is embedded in the first through hole. The outer diameter of the light-shielding plate mounting part matches the diameter of the second through hole. The light-shielding plate mounting part passes through the second through hole, and the light-shielding plate mounting part has a plurality of split pins.

[0008] One end of the reset spring abuts against the connection between the keycap and the light shield mounting part, and the other end abuts against the first step.

[0009] The light-shielding plate includes a light-shielding part and a mounting part connected to the light-shielding part. The mounting part includes a first column connected to the light-shielding part and a second column connected to the first column. The first column is cuboid and the second column is cylindrical. The mounting part of the light-shielding plate is hollow and has a second step.

[0010] The base is provided with two symmetrically arranged mounting clips.

[0011] Beneficial effects Compared with the prior art, the present invention has at least the following beneficial effects: 1) By placing the light-transmitting base and the indicator light close together, the button's open / closed status can be displayed intuitively, forming a three-in-one integrated structure that facilitates quick identification on-site.

[0012] 2) The four-part plug structure and the snap-locking with barbed plugs make the button automatically lock after being pressed into the base, and it is vibration-resistant and not easy to come out.

[0013] 3) The reset spring is located inside the base and is surrounded by the base and button, making it dustproof and moistureproof, thus improving durability and lifespan.

[0014] 4) The sunshade adopts a replaceable independent design, and the friction is increased by the combination of columns / steps, making it less likely to slip out, while also making maintenance and replacement convenient.

[0015] 5) The light-shielding plate extends to block the light path when pressed and retracts to release the light when released, which can form a stable light path switching control with the optocoupler sensor and is suitable for single-spindle start-stop control scenarios.

[0022] The present invention will be further described below with reference to embodiments. It should be understood that the following embodiments are only used to explain the present invention and are not intended to limit the scope of protection of the present invention.

[0023] Please see Figure 1-6 This utility model provides an optocoupler switch button assembly for installation at the spindle box on the ring rail of a spinning machine to control the start and stop of a single spindle. The button assembly includes a button 1, a base 2, a light-shielding plate 6, and a return spring 4 disposed within the base 2. The button 1 is mounted on the base 2 and can reciprocate linearly relative to the base 2 in the pressing direction. The return spring 4 is disposed inside the base 2 and abuts against both the button 1 and the base 2, providing a restoring force after the button 1 is released, causing the button 1 to automatically return to its original position. The spring 4 is surrounded by the base 2 and not exposed, thus providing dust and moisture protection and improving durability.

[0024] The base 2 is positioned close to the open / closed status indicator light on the control panel. The base 2 is made of a light-transmitting material (such as transparent or semi-transparent material, as long as it can transmit light, it meets the requirements of this utility model), so that the brightness changes of the open / closed status indicator light can be presented through the base 2 to indicate the open / closed status of the button; thus forming a three-in-one integrated effect of button, base and indicator display, which makes it easy for the operator to quickly identify the status of the electric ingot on site.

[0025] The base 2 is provided with two symmetrically arranged mounting clips 21, which are used to reliably install the base 2 to the corresponding mounting position (e.g., mounting hole / opening) of the electric ingot box, so as to ensure the assembly stability of the button assembly under vibration environment.

[0026] In this embodiment, the button 1 has multiple separate pins extending in the pressing direction on the side facing the base 2. Preferably, there are four separate pins, two of which are oppositely arranged pins 5 with barbs, and the other two are oppositely arranged pins 3 without barbs. The ends of the pins 5 with barbs have barb structures; when the button 1 is pressed into the base 2 from the outside, the four separate pins use the elasticity of their separate structures to generate radial elasticity to give way. After the barbs pass the limiting part of the base 2, they automatically spring back, so that the barbs hook onto the base 2, thereby completing the locking assembly of the button 1 and the base 2, making it difficult for the button 1 to be removed from the base 2.

[0027] At the same time, under the pressure of the base 2, the multiple split pins can also clamp the light shield 6 located between the multiple split pins through their own elasticity, thereby limiting the position of the light shield 6 and preventing it from falling, thus improving the reliability of the light shield 6 under long-term pressing cycles.

[0028] In a further improvement of this embodiment, the base 2 is a hollow structure, forming a first through hole and a second through hole that are interconnected, and a first step is formed at the connection between the first through hole and the second through hole.

[0029] Button 1 includes a keycap 12 and a light-shielding plate mounting part 14 connected to the keycap 12. A return spring 4 is sleeved on the light-shielding plate mounting part 14; the outer diameter of the keycap matches the diameter of the first through hole, the bottom of the keycap is embedded in the first through hole and moves axially along the first through hole when pressed to avoid dust accumulation; the outer diameter of the light-shielding plate mounting part matches the diameter of the second through hole, the light-shielding plate mounting part passes through the second through hole, and forms the aforementioned multiple split pins at its end to achieve locking assembly with the base 2.

[0030] One end of the return spring 4 abuts against the connection between the keycap and the light shield mounting part, and the other end abuts against the first step. The first step axially positions the spring 4, which can prevent the spring 4 from deflecting or moving, and ensure the consistency of the feel and the reliability of the reset of the button 1.

[0031] The light shield 6 includes a light shielding part 62 and a mounting part 64 connected to the light shielding part 62. The light shielding part 62 and the mounting part 64 are at a certain angle, preferably 90 degrees. The mounting part 64 includes a first column connected to the light shielding part 62 and a second column connected to the first column. The first column is cuboid and the second column is cylindrical. The light shield mounting part 14 of the button 1 is hollow and has a second step to ensure a reliable axial limiting fit after the light shield 6 is assembled.

[0032] A light-shielding plate 6 is positioned between multiple separate pins and is linked to button 1: when button 1 is pressed and moves inward toward the base 2, the light-shielding plate 6 extends outward relative to the base 2 and enters the optical path area of ​​the optocoupler sensor to block the light; when button 1 is released, the light-shielding plate 6 retracts under the action of the reset spring 4, releasing the obstruction of the optical path, thereby realizing the switching control of the optical path state. The light-shielding plate 6 can be designed independently and engages with button 1 via a column / step to increase friction, reduce the risk of slippage, and facilitate replacement and maintenance.

[0033] This button assembly works in conjunction with the optocoupler sensor and control board inside the ingot box: when the operator presses button 1, the light shield 6 extends outward and blocks the light path of the optocoupler sensor. After receiving the change in the optocoupler signal, the control board can output a stop / start control signal according to preset logic (for example, a delay-based stop logic can be set) to stop the corresponding ingot from operating. When the external force is released, the light shield 6 retracts under the action of the spring, and the control board maintains the corresponding state recognition to realize the cyclic control of the ingot's start and stop.

[0034] In addition, for ease of on-site maintenance: 1) When replacing the light shield 6, you can press button 1 to make the light shield 6 pop out / extend to a position that is easy to grab before performing the replacement operation.

[0035] 2) If button 1 needs to be replaced, it is preferable to press button 1 first and remove the light shield 6, then use your fingers to press the two barbed pins 5 and compress them inward so that the barbs are disengaged from the buckle limit of the base 2, thereby removing button 1 from the base 2 to complete the replacement.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
