[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] An embodiment of this utility model provides a scraper device (hereinafter referred to as "scraper device") suitable for servo feed rollers in uncoiling and blanking lines. See [link to relevant documentation]. Figure 1-9The servo feed roller 1 of the uncoiling and blanking line is mounted on the frame 2. The scraper device 3 includes a scraper assembly 4 and a position adjustment mechanism 5.

[0029] See Figure 4-5 The scraper device has a scraper assembly 4 mounted on the frame via bearing seats 6. Two bearing seats are mounted on both sides of the frame 2 via fixing plates (fixing plates are fixed to the frame with screws), providing good support. The scraper assembly 4 has two rotating shafts 4a coaxially distributed on the bearing seats (both rotating shafts can suspend and support the scraper, with one shaft also serving to push the scraper assembly away from or towards the working position), a scraper bracket 4c mounted between the rotating shafts via fixing blocks 4b, and a scraper 4e mounted on the scraper bracket and cooperating with the servo feed roller of the uncoiling and blanking line. The scraper bracket is an L-shaped steel plate, and a stepped structure is provided at the scraper mounting position to facilitate embedded scraper installation. The scraper can be fixed in a detachable manner or with adhesive. For ease of maintenance, a detachable fixing method is preferred. The scraper is made of fiberglass, which does not damage the feed roller surface and is cost-effective. The scraper bracket 4c is equipped with a scraper pressure plate 4d and a dust collection box 4f. The scraper pressure plate is fixed to the scraper bracket with screws and can clamp and fix the scraper with the scraper bracket. The dust collection box 4f is used to store impurities scraped off the roller surface. The dust collection box has a vertical plate perpendicular to the scraper connecting plate set on the scraper bracket and corner plates set on both sides of the vertical plate. The rotating shaft 4a passes through the bearing seat 6 and is connected to the fixing block 4b. The fixing block 4b and the pressure plate are fixed to the scraper bracket with bolts. The pressure plate and the scraper bracket clamp the scraper in the middle.

[0030] See Figure 6-8The position adjustment mechanism 5, installed on the frame and used to adjust the scraper assembly, can adjust the scraper assembly to or away from the working position. The position adjustment mechanism 5 includes a position adjustment mechanism fixing seat 5a set on the frame. The position adjustment mechanism fixing seat 5a is a fixed plate arranged on the frame and adjacent to the bearing seat. The position adjustment mechanism fixing seat is distributed on the frame and close to one of the bearing seats to facilitate the corresponding adjustment of the scraper assembly. The rotary positioning plate 5b set on the position adjustment mechanism fixing seat is provided with an arc-shaped rotary guide groove 5b-1. The arc-shaped rotary guide groove can be generally C-shaped. The two ends of the arc-shaped rotary guide groove are provided with non-working position limit points and working position limit points. For example, non-working position limit holes and working position limit holes are respectively provided at the two ends of the arc-shaped rotary guide groove to cooperate with the pin 5c located there. The handle 5d, mounted on the side of the rotating positioning plate via pin 5e, allows for manual adjustment of the scraper position. A pin 5c is located in the middle of the handle, with one end positioned in the arc-shaped rotating guide groove 5b-1 on the rotating positioning plate. The adjusting sleeve assembly 5g, connected to the handle, is suspended on the side of the frame. This assembly includes an adjusting sleeve 5g-1 connected to the handle via a pin. A compression spring 5g-2 is located in the inner hole of the adjusting sleeve 5g-1. An adjusting rod 5g-4, with one end engaging with the compression spring, is mounted on the adjusting sleeve via a fixing block 5g-3. The other end of the adjusting rod is connected to a clamping block via a rotating support 5g-5. The clamping block 5f, connected to the adjusting sleeve assembly and clamped at the rotating shaft of the scraper assembly, connects to the rotating shaft 4a. In this embodiment, the position adjustment structure is only set in… Figure 1 At the rear bearing housing, a single position adjustment structure is sufficient to meet the requirements.

[0031] See Figure 9 The pin 5c is equipped with a return spring 5c-1. A reduced diameter rod is provided on the pin body located in the handle hole to meet the installation requirements of the return spring. The spring is secured by the stepped structure between the reduced diameter rod and the pin, so that the differential pin set in the handle constitutes a self-locking pin.

[0032] As an improvement, a rubber washer can be provided at the end of the rotating shaft used to install the position adjustment mechanism 5, so as to reduce the impact of equipment vibration on the structure of the position adjustment mechanism 5 by fixing the clamping block at the rubber washer.

[0033] A scraper device is added to the lower roller of the servo feeder to clean the surface of the lower roller. The working principle of this utility model is described in detail below:

[0034] The handle 5d is equipped with a self-locking pin (formed by a pin with a return spring 5c-1). The rotating positioning plate 5b has a guide groove with limit points (non-working position) and extreme points (working position) at both ends. The self-locking pin moves in the guide groove and locks itself when it enters the limit point or extreme point. The scraper device is manually adjusted via the handle 5d, with two scraper positions (position 1: scraper working position, such as...). Figure 2 As shown; Position 2: Scraper in non-working position, such as Figure 3 (As shown) - Position 1 is in contact with the upper and lower rollers by the weight of the scraper and the spring. Position 2 allows the scraper to disengage from the upper and lower rollers by self-locking at the limit point. When switching from position 1 to position 2, the handle causes the self-locking pin to enter the limit point. When switching from position 2 to position 1, the self-locking pin is pulled outward to disengage from the limit point and adjusts itself to the contact position.

[0035] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
