Description

Technical Field

[0001] This utility model relates to the field of cold rolling equipment, and in particular to a scraper device for cleaning the surface of a support roller. Background Technology

[0002] In the normal production process of cold rolling mills, various types of support roll cleaners are used, which can be broadly categorized into two types: mechanical fixed scraper devices and hydraulic motor reciprocating cleaning devices. Mechanical fixed scraper devices require scraper position adjustment before each rolling cycle, leading to frequent personnel entry and exit from the stand and impacting work efficiency. Hydraulic motor reciprocating cleaning devices are easy to operate; simply turning the switch while powered on initiates cleaning. However, if the hydraulic lines leak, the oil from the hydraulic lines will mix with the rolling oil, affecting the rolling process. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a scraper device for cleaning the surface of a support roller. The present utility model adopts the following technical solution:

[0004] This utility model discloses a scraper device for cleaning the surface of a support roller, comprising a scraper clamp, a scraper blade at the bottom of the scraper clamp, and a travel limit rod and a lifting and stabilizing rod at the top of the scraper clamp; the travel limit rod passes through a pre-drilled hole on a fixed frame and is threadedly connected to a limit nut; an elastic element is provided on the travel limit rod, one end of which abuts against the fixed frame and the other end against the scraper clamp; a guide sleeve is slidably connected to the lifting and stabilizing rod, and the guide sleeve is fixedly connected to the fixed frame; the fixed frame is connected to a pneumatic telescopic drive assembly.

[0005] Preferably, the scraper clamp includes an intermediate body, and clamping plates are provided on both sides of the intermediate body. The clamping plates on both sides and the intermediate body are fixed together by bolt assembly; a scraper is provided between each clamping plate and the intermediate body.

[0006] Preferably, the scraper is made of resin.

[0007] Preferably, the pneumatic telescopic drive assembly includes two cylinders, which are respectively arranged at both ends of the fixed frame. The telescopic ends of the two cylinders are fixed to the gantry frame, and the gantry frame is fixedly connected to the fixed frame.

[0008] Preferably, the elastic element is a spring.

[0009] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0010] This utility model uses a pneumatically driven cylinder extension and retraction method to control the overall lifting and lowering of the scraper. At the same time, the scraper uses a spring buffer to form a pre-pressure on the support roller surface, ensuring that it does not scratch the support roller surface and can effectively clean the oil film on the roller surface.

Detailed Implementation

[0015] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 and 2 As shown in the figure, this embodiment discloses a scraper device for cleaning the surface of a support roller, including a scraper clamp 1, a scraper 2 is provided at the bottom of the scraper clamp 1, and a stroke limit rod 3 and a lifting and stabilizing rod 4 are fixed at the top of the scraper clamp 1.

[0017] The travel limit rod 3 passes through a pre-drilled hole in the fixing frame 5 and is threadedly connected to the limit nut 301. Rotating the limit nut 301 adjusts the travel range of the scraper clamp 1. To ensure the preload between the scraper 2 and the support roller 9, an elastic element 6 is provided on the travel limit rod 3. One end of the elastic element 6 abuts against the fixing frame 5, and the other end abuts against the scraper clamp 1. Specifically, the elastic element 6 can be a spring, which is sleeved on the travel limit rod 3.

[0018] Among them, the lifting stabilizer bar 4 is used to ensure the stability of the scraper 2. The lifting stabilizer bar 4 is slidably connected to the guide sleeve 7, and the guide sleeve 7 is fixedly connected to the fixed frame 5.

[0019] The upper part of the fixed frame 5 is connected to a pneumatic telescopic drive assembly 8. The pneumatic telescopic drive assembly 8 drives the fixed frame 5 to move up and down. The pneumatic telescopic drive assembly 8 includes two cylinders 801, which are respectively arranged at both ends of the fixed frame 5. The telescopic ends of the two cylinders 801 are fixed to a portal frame 802, which is fixedly connected to the fixed frame 5. The upper ends of the two cylinders 801 are connected to the roof or other fixed supports to form a suspension system.

[0020] like Figure 2 As shown, the scraper clamp 1 includes an intermediate body 101. The top of the intermediate body 101 is fixed to the travel limit rod 3 and the lifting stabilizer rod 4. Clamping plates 102 are provided on both sides of the intermediate body 101. A scraper 2 is provided between each clamping plate 102 and the intermediate body 101. The clamping plates 102, scraper 2, and intermediate body 101 on both sides are fixed together by bolt assembly 103. The scraper 2 can be made of resin.
