Abstract

This utility model discloses an aluminum foil roller scraper, including a scraper assembly detachably connected to a support frame via a connecting groove. The lower end of the support frame is hinged to a fixed base. A first spring in the connecting groove abuts against the scraper assembly to achieve floating compensation. A ball bearing inside the transverse blind hole, in conjunction with a second spring, forms a transverse fine-tuning structure with the groove of the scraper assembly. The angle locking mechanism uses an arc-shaped plate extending from the support frame to attract an electromagnet in the fixed base, achieving double locking with a threaded nut at the end of the hinge shaft. The scraper assembly has an embedded reinforcing mesh and is covered with a rubber scraper with oblique serrated texture, improving scraping rigidity and flow guiding effect. The fixed base is equipped with a recovery tank connected to an oil storage tank, and waste oil is recovered through an oil collection hole and a filter screen. Simultaneously, the oil flow cools the electromagnet. This device improves scraping stability through floating compensation, integrates oil recovery and cooling functions, and features self-adjustment, easy maintenance, and high efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil production equipment, specifically to an aluminum foil roller scraper. Background Technology

[0002] During the aluminum foil rolling process, the roller surface often needs to be coated with rolling oil for lubrication and cooling. After rolling, the oil on the aluminum foil roller surface needs to be scraped off in time; otherwise, the oil on the roller surface may adhere to the aluminum foil surface as the roller rotates, forming oil spots, streaks, or uneven brightness, affecting the uniformity of the aluminum foil's appearance. Fluctuations in oil film thickness can also interfere with the uniform transmission of rolling force, causing local thickness deviations in the aluminum foil (such as wavy edges, thicker in the middle and thinner at the edges), reducing the product qualification rate. Existing scraper blades are mostly fixed single rubber plate structures with non-adjustable scraper angles. When the scraper wears out, the entire blade must be replaced. In addition, existing scraper blades are prone to skew and deviation due to roller friction, leading to failure of the scraping function. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings mentioned in the background art and provide an aluminum foil roller scraper.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] An aluminum foil roller scraper includes a scraper assembly and a support frame detachably connected to the scraper assembly via a connecting groove. The lower end of the support frame is hinged to a fixed base, and the hinge point is located on the extension line of the tangent direction of the roller. A first spring is provided in the connecting groove, and the two ends of the first spring abut against the inner side of the connecting groove and the scraper assembly, respectively. An angle locking mechanism is provided at the hinge point between the support frame and the fixed base.

[0006] Furthermore, the connecting groove is provided with a blind hole in the transverse direction. A ball and a second spring are provided in the blind hole. The two ends of the second spring abut against the ball and the blind hole respectively. The ball is exposed in the blind hole by the elastic force of the second spring. The scraper assembly is provided with a groove that adapts to the blind hole. The groove extends along the direction of the connecting groove. The scraper assembly slides back and forth along the groove.

[0007] Furthermore, the angle locking mechanism includes: an arc-shaped plate extending from the support frame to the fixed base, the arc-shaped plate being partially embedded in the fixed base, the surface of the arc-shaped plate being provided with an electromagnet adapted to the arc-shaped plate provided on the fixed base, the electromagnet being connected to a power source and attracting the arc-shaped plate when energized.

[0008] Furthermore, the angle locking mechanism includes: a hinge shaft is provided between the support frame and the fixed base, the end of the hinge shaft passes through the fixed base and is threaded, and a nut is connected to the thread.

[0009] Furthermore, the scraper assembly is provided with a reinforcing mesh inside, the reinforcing mesh covers the rubber scraper, and the contact surface between the rubber scraper and the roller is provided with an oblique serrated texture.

[0010] Furthermore, a spring seat is slidably provided at one end of the first spring that abuts against the connecting groove, the support frame is provided with an adjustment hole communicating with the connecting groove, a threaded rod is provided through the adjustment hole on the spring seat, and a nut is provided on the outside of the support frame on the threaded rod.

[0015] The advantages and beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a first spring in the connecting groove to cooperate with a slidably arranged scraper assembly, so that the scraper assembly has a floating amount along the length direction of the first spring. The ball bearing and the second spring realize the lateral fine adjustment of the scraper, automatically compensate for the offset or vibration of the roller, and make the oil scraping more uniform and stable.

[0017] 2. The electromagnet attracts the arc plate to achieve quick angle locking, meeting the needs of multi-angle adjustment. The threaded nut at the end of the hinge shaft provides mechanical secondary locking, improving working stability.

[0018] 3. The structure of the fixed base forming a recycling trough and connecting to the oil storage tank, as well as the serrated texture of the scraper assembly, enable the scraped oil to be effectively collected. During the collection process, the flowing oil can cool the fixed base and prevent the electromagnet from overheating during long-term operation.

[0019] 4. The reinforced mesh enhances the rigidity of the rubber scraper, reducing its deformation caused by the rotation of the roller, thereby improving the oil scraping efficiency. Attached Figure Description

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0033] Example 1

[0034] Please see Figures 1-2 This embodiment provides a specific implementation of an aluminum foil roller scraper, including the following structure: The scraper assembly 1 consists of a rubber scraper 13 and an internally embedded metal reinforcing mesh 12. The contact surface of the rubber scraper 13 is processed with a transverse oblique serrated texture 14 to enhance the scraping effect and reduce frictional resistance. The scraper assembly 1 is detachably connected to the support frame 3 via a connecting groove 2. A first spring 5 is provided in the connecting groove 2, one end of which abuts against the scraper assembly 1, and the other end is slidably connected to the inner side of the connecting groove 2 via a spring seat 8. An adjustment hole 31 is provided on the side wall of the support frame 3. The threaded rod 81 of the spring seat 8 passes through the adjustment hole 31 and is fixed by a nut 82. Rotating the nut 82 can adjust the preload of the first spring 5, thereby controlling the pressure of the scraper assembly 1 on the roller.

[0035] The lower end of the support frame 3 is hinged to the fixed base 4, with the hinge point located on the extension line of the roller tangent direction, ensuring a stable contact angle between the scraper assembly 1 and the roller. The angle locking mechanism 6 uses the cooperation of an electromagnet 62 and an arc plate 61: the arc plate 61 extending from the support frame 3 is embedded in the fixed base 4, and the electromagnet 62 is installed inside the fixed base 4. When energized, the arc plate 61 is attracted to lock the angle. The adjustment hole 31 and the surface of the arc plate 61 are marked with scale lines 9, which facilitates precise adjustment of the spring pressure and the angle of the support frame. Here, the electromagnet 62 can be embedded in the fixed base 4, using a non-contact connection with the arc plate 61. Although there is a certain loss of magnetic force, it can seal and prevent oil from entering the fixed base and affecting the circuit connection.

[0036] The top of the fixed base 4 is provided with an annular recovery trough 41, which is connected to the oil storage tank 43 below through a filter screen 42. The oil storage tank 43 is detachably installed at the bottom of the fixed base 4, and the oil collection hole 44 of the fixed base 4 guides the scraped oil into the oil storage tank 43. The oil storage tank 43 is designed to be detachable, specifically by means of a snap-fit ​​structure, for easy cleaning and maintenance.

[0037] A blind hole 21 is laterally opened on the side wall of the connecting groove 2. A ball bearing 22 and a second spring 23 are installed in the blind hole 21. The second spring 23 pushes the ball bearing 22 partially out of the blind hole 21. The groove 11 of the scraper assembly 1 cooperates with the ball bearing 22, allowing the scraper assembly 1 to slide along the direction of the connecting groove 2 to adapt to the slight deformation or vibration of the roller, while reducing wear.

[0038] Example 2

[0039] This embodiment provides another implementation method, the main difference from embodiment 1 being the angle locking mechanism and adjustment method: the support frame 3 and the fixed base 4 are connected by a hinge shaft 7, the end of the hinge shaft 7 is provided with a thread 71 and is locked by a nut 72. Tightening the nut 72 can fix the angle of the support frame 3, and after loosening, the tilt angle of the support frame 3 can be manually adjusted to realize the adjustment of the contact pressure of the scraper assembly 1.

[0040] The spring seat 8 of the first spring 5 adopts a threaded rod 81 structure, with nuts 82 symmetrically arranged on both sides to ensure uniform force distribution on the scraper assembly 1. The remaining structure is the same as in Embodiment 1, including the ball bearing 22 sliding mechanism, the recovery tank 41, and the oil storage tank 43 system.

[0041] The working principle of this invention is as follows: the fixed base 4 is fixed to the side of the roller, the angle of the support frame 3 is adjusted so that the scraper assembly 1 is in contact with the roller surface, and the target angle is aligned by the scale line 9 before locking the electromagnet by energizing it or tightening the nut. Rotating the nut 82 changes the compression of the first spring 5, and combined with the sliding mechanism of the ball bearing 22, adaptive pressure adjustment is achieved. The scraped oil flows into the oil storage tank 43 through the recovery tank 41 and the filter screen 42. The oil storage tank 43 is periodically disassembled to clean the waste oil.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
