Description

Technical Field

[0001] This utility model relates to the field of roller protection technology, specifically a protective device for the connection of the tail roller of a spinning machine. Background Technology

[0002] The spinning frame is a key piece of equipment in the spinning process, and its drafting mechanism consists of multiple rollers.

[0003] The roller is the core component of a spinning machine, directly affecting yarn quality and production efficiency. The following is a detailed analysis from the aspects of function, structure, materials, process, and maintenance: The roller is a key component in textile machinery for achieving fiber drafting and conveying. Through a pair of upper rollers (lead rollers) and lower rollers forming a gripping jaw, it draws roving into fine yarn.

[0004] These rollers are typically driven in series via a transmission mechanism at the rear of the spinning frame (the transmission mechanism is located within the roller support, not shown in the diagram). During long-term high-speed operation of the spinning frame, significant safety hazards and maintenance issues arise at the rear roller connection point: Entanglement risk: Yarn or fly waste can easily become entangled on the high-speed rotating roller connecting shaft, coupling, and exposed bolts. If entanglement occurs and is not detected by the operator in time or addressed before the equipment has completely stopped, it can easily lead to arms or clothing being caught, causing serious personal injury. Lubrication contamination: Entangled fly waste mixes with lubricating grease, forming oily clumps that not only contaminate the yarn and affect yarn quality but also hinder normal heat dissipation at lubrication points, accelerating wear on transmission components. Difficulty in inspection and cleaning: The exposed connection point requires operators to be extra careful during daily inspections and cleaning, increasing workload and psychological burden.

[0027] The upper cover plate 5 is symmetrically connected to both sides of the mounting plate 4, and the side plate 7 is connected to the bottom of the upper cover plate 5 on the side away from the mounting plate 4. The bottom of the side plate 7 is provided with an arc-shaped groove 8 that matches the shape of the roller 3.

[0028] Analysis of the above content: This solution is based on an integrated structure composed of mounting plate 4, upper cover plate 5 and side plate 7, which covers the connection between rotating shaft 2 and roller 3 to prevent yarn from entering the gaps due to movement and causing yarn tangling.

[0029] When operators are in operation, the mounting plate 4, the upper cover plate 5, and the side plate 7 protect them from direct contact with the rotating shaft 2, thus providing a certain degree of protection for the operators.

[0030] like Figure 3 As shown, the yarn passes between the two rollers 3 and is pulled by the rollers 3. The yarn is blocked by the side plate 7 and cannot enter the connection between the rotating shaft 2 and the rollers 3.

[0031] The structure used to drive the rotation of the rotating shaft 2 and the roller 3 is inside the roller support 1 and adopts existing technology. It is not shown in the figure. The structure of roller support 1, rotating shaft 2, roller 3 and so on is an existing schematic diagram. Differences from the actual figure do not affect the understanding of this solution.
