Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically a protective mechanism for a photoelectric sensor on the doffing track of a roving frame. Background Technology

[0002] Modern roving frames are generally equipped with an automatic doffing system, which uses a doffing chain that travels along a track to automatically exchange empty and full yarn tubes.

[0003] To ensure accurate positioning and orderly operation, multiple photoelectric sensors (such as through-beam and reflective types) are installed at key locations along the track to detect the position of the trolley, the status of the spindles, etc. The photoelectric sensors are affected by collisions or scratches.

[0004] Physical collision: During high-speed operation or debugging, the doffing carriage may directly collide with the sensor body or its support due to positioning deviation, inertia, or other reasons, resulting in sensor breakage, support deformation, or displacement.

[0005] Indirect scratching and squeezing: When changing yarn carts, performing equipment maintenance or routine cleaning, the tools used by operators, the transported yarn carts or other equipment parts are very likely to scratch or squeeze the exposed sensors. Utility Model Content

[0006] The purpose of this invention is to provide a protective mechanism for a photoelectric sensor on the doffing track of a roving frame, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for a photoelectric sensor on a roving frame doffing track, comprising:

[0008] baffle and connecting part;

[0009] The baffle is a bent sheet, and the internal space of the baffle surrounds the outside of the photoelectric sensor. The two ends of the baffle are located outside the photoelectric sensor and are fixed to the two ends of the baffle by a connecting part.

[0010] Preferably, the bend of the baffle is designed as an arc-shaped surface.

[0011] Preferably, the baffle is made of stainless steel.

[0012] Preferably, the connecting part includes a snap-fit ​​frame disposed at one end of the baffle, and a fixing plate is connected to the other end of the baffle, and the fixing plate is provided with a connecting hole.

[0013] Preferably, the connecting part includes connecting plates disposed at both ends of the baffle, and adhesive strips are disposed on the connecting plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This solution can effectively resist direct collisions and indirect scratches without affecting the normal detection function of the sensor.

[0016] Effective collision protection: The bent baffle forms the first line of physical defense, which can directly withstand and resist accidental impacts from the doffing trolley or tools, protecting the internal core sensors from damage.

[0017] Guiding and stress relief: The bending point can convert the frontal impact into lateral sliding force, cleverly "dissipating" the impact instead of "bearing" it, which greatly improves the impact resistance performance.

[0018] Dust and dirt prevention: Effectively prevents flying shavings and oil stains from falling directly onto the sensor surface, avoiding impact, reducing cleaning frequency, and also reducing the risk of damage during the cleaning process. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1:

[0027] Please see Figure 1-4 This utility model provides a technical solution: a protective mechanism for a photoelectric sensor on the doffing track of a roving frame, comprising: a baffle 4 and a connecting part;

[0028] The baffle 4 is a bent sheet, the bent part of the baffle 4 is set as an arc surface, and the internal space of the bent baffle 4 surrounds the outside of the photoelectric sensor 3. The two ends of the baffle 4 are located outside the photoelectric sensor 3, and the two ends of the baffle 4 are fixed by a connecting part.

[0029] Analysis of the above content: The bending of baffle 4 is formed by folding the flat baffle 4 in half, and the bending of baffle 4 forms... Figure 2 , Figure 4 With this structural form, the curved baffle 4 can accommodate the photoelectric sensor 3 inside. The two ends of the baffle 4 (i.e. the two edges that are close together after being folded) are fixed in the installation position by the connecting part, so that the baffle 4 can stably surround the outside of the photoelectric sensor 3.

[0030] Example 2:

[0031] Please see Figure 1-4 This utility model provides a technical solution: the baffle 4 is made of stainless steel.

[0032] Analysis of the above: Stainless steel baffle 4 has good impact resistance, and aluminum alloy and other materials can also be used as alternatives.

[0035] Analysis of the above content: This embodiment adopts the first type of connecting part structure, that is, this connecting part includes a fixing plate 5, a connecting hole 6, and a snap-fit ​​frame 7, as shown below. Figure 1As shown, the photoelectric sensor 3 is mounted on the roving frame 1 via a Z-shaped sensor bracket 2 (the roving frame 1 shown here is only a part and is a schematic diagram; it does not fully represent the roving frame 1 and does not involve the operation of the roving frame. It is only used to understand the connection between the baffle 4 and the sensor bracket 2). Figure 1 The part shown is the spindle part of the roving frame. The snap-fit ​​frame 7 can be snapped onto the upper end of the sensor bracket 2 of this shape, and the lower side is screwed to the sensor bracket 2 through the connecting hole 6 by a screw.
