[0061] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0062] like Figures 1 to 10 As shown, the present invention provides a scraping device, which includes a feeding mechanism 1, a scraping tape 2, a positioning mechanism 4, a pulling mechanism 5, a feeding mechanism 6 and a shearing mechanism 7. The scraping tape 2 has a fixed end and a movable end (that is, the scraping tape 2 has two ends, one end is a fixed end, and the other end is a movable end); the feeding mechanism 1 is used to store and output the scraping tape 2 to the outside, the fixed end of the scraping tape 2 is located inside the feeding mechanism 1, and the movable end of the scraping tape 2 is located outside the feeding mechanism 1 and passes through the positioning mechanism 4. At least part of the position of the scraping tape 2 is pressed by the positioning mechanism 4; the pulling mechanism 5 can at least move between a first position close to the positioning mechanism 4 and a second position away from the positioning mechanism 4. When When the pulling mechanism 5 is in the first position, the pulling mechanism 5 clamps the movable end of the scraping tape 2; when the pulling mechanism 5 is in the second position, the scraping tape 2 located between the pulling mechanism 5 and the positioning mechanism 4 is straightened; the feeding mechanism 6 can move between the pulling mechanism 5 and the positioning mechanism 4 and clamp one section of the scraping tape 2 as the scraping segment; the shearing mechanism 7 can at least move between the pulling mechanism 5 and the positioning mechanism 4, and respectively disconnect the scraping tape 2 located between the positioning mechanism 4 and the feeding mechanism 6 and between the pulling mechanism 5 and the feeding mechanism 6, so as to retain the scraping segment on the feeding mechanism 6; the feeding mechanism 6 can carry the scraping segment to the position of the glue gun 3 to scrape off the residual glue on the glue gun 3.

[0063] In the present invention, a scraper tape 2 is stored in the feeding mechanism 1, and the movable end of the scraper tape 2 extends to the outside of the feeding mechanism 1. The positioning mechanism 4 is used to press and position at least a portion of the scraper tape 2 located outside the feeding mechanism 1, so that the pulling mechanism 5 can accurately find the movable end of the scraper tape 2 and clamp it when it moves to the second position. In the present invention, a movable pulling mechanism 5 is provided on one side of the positioning mechanism 4, and the pulling mechanism 5 can move at least between a first position close to the positioning mechanism 4 and a second position away from the positioning mechanism 4. When the pulling mechanism 5 is in the first position, the pulling mechanism 5 can clamp the movable end of the scraping tape 2 which is in a pressed and positioned state by the positioning mechanism 4, and then the pulling mechanism 5 can pull the scraping tape 2 to move to the second position away from the positioning mechanism 4; when the pulling mechanism 5 moves to the second position, the scraping tape 2 between the pulling mechanism 5 and the positioning mechanism 4 is in a straightened state, in which case the feeding mechanism 6 can be moved between the pulling mechanism 5 and the positioning mechanism 4, and a section of the straightened scraping tape 2 between the pulling mechanism 5 and the positioning mechanism 4 can be clamped by the feeding mechanism 6 as a scraping section; after determining the scraping section, the scraping tape 2 can be moved between the pulling mechanism 5 and the positioning mechanism 4 The scraping mechanism 7 is moved between the positioning mechanism 4 and the feeding mechanism 6, and the scraping tape 2 between the positioning mechanism 4 and the feeding mechanism 6 and the scraping tape 2 between the pulling mechanism 5 and the feeding mechanism 6 are cut by the shearing mechanism 7 respectively, so that the above-mentioned clamped scraping glue segment can be retained on the feeding mechanism 6, and then the scraping glue segment can be moved to the position of the glue gun 3 by the feeding mechanism 6 to scrape off the residual glue on the glue gun 3. After the scraping is completed, the scraping glue segment clamped by the feeding mechanism 6 can be released and it can fall off automatically. The above operation can be repeated to repeat the scraping operation. Since each scraping uses a re-clamped and sheared scraping glue segment, there will be no residual glue remaining after repeated use of the scraping segment, which ensures the scraping effect and product quality. There is no need to manually clean the residual glue during the entire scraping process, and the normal operation of the equipment will not be affected in the scraping state, which saves costs and effectively improves production efficiency.

Positioning holes for positioning are provided between different tube bodies. Positioning between different tube bodies can be achieved by inserting positioning pins into the positioning holes. When the length of the telescopic column needs to be adjusted, the positioning pins are removed, the telescopic position between different tube bodies is changed, and the positioning pins are then inserted into the corresponding positioning holes to achieve the length adjustment of the telescopic column. Of course, the structure of the telescopic column is not limited to the above-mentioned telescopic sleeve structure, and can also be other telescopic tube structures.

[0077] In an optional embodiment of the present invention, Figures 1 to 7 、 Figure 10 As shown, the feeding mechanism 6 includes two second clamps 601 arranged side by side in the horizontal direction, with a gap 609 between the two second clamps 601, so that the scraping tape 2 clamped by the two second clamps 601 and located between the two second clamps 601 is used as a scraping segment; the two second clamps 601 are connected to the vertically arranged fourth mounting plate 603 through a third lifting device 602 to drive the two second clamps 601 to move up and down; the fourth mounting plate 603 is connected to the column 8 through a third translation device 604 to drive the two second clamps 601 to move in the horizontal direction.

[0078] In which, when the pulling mechanism 5 is in the second position, the spacing distance between the pulling mechanism 5 and the positioning mechanism 4 is greater than the spacing distance between the two second clamps 601 (that is, the two second clamps 601 are located between the pulling mechanism 5 and the positioning mechanism 4), so that the two second clamps 601 can clamp a section of the scraper tape 2 located between the pulling mechanism 5 and the positioning mechanism 4.

[0079] Furthermore, the third lifting device 602 may be, but is not limited to, a third lifting cylinder.

The pinch wheel 401 cooperates with the pinch plate 402 to press and position the scraper tape 2. The first clamp 501 of the pulling mechanism 5 is controlled to move to the first position close to the positioning mechanism 4 and the scraper tape 2 is pressed. 2 is clamped, and the first clamp 501 clamps the movable end of the scraping tape 2 and drives the scraping tape 2 to move to the second position away from the positioning mechanism 4 until the first clamp 501 moves to the second position to straighten the scraping tape 2; the two second clamps 601 of the feeding mechanism 6 are controlled to move to between the pulling mechanism 5 and the positioning mechanism 4, and the two second clamps 601 clamp a section of the scraping tape 2 between the pulling mechanism 5 and the positioning mechanism 4 as the scraping section, and the scraping tape 2 is straightened by the two second clamps 601. The clamping of the adhesive tape 2 can prevent the scraping tape 2 from running out of position; thereafter, the shearing device 701 is controlled to move between the pulling mechanism 5 and the positioning mechanism 4, and the scraping tape 2 located between the positioning mechanism 4 and the feeding mechanism 6 and the scraping tape 2 located between the pulling mechanism 5 and the feeding mechanism 6 are cut respectively, and the remaining scraping tape segments are stably clamped by the two second clamps 601; at this time, the first clamp 501 can be loosened, and a portion of the scraping tape 2 clamped by the first clamp 501 falls directly into the collection bucket below The first lifting device 11 drives the mounting platform 12 upward (i.e., moves the positioning mechanism 4 and the material pulling mechanism 5 away) to prevent them from interfering with the scraping process. The two second clamps 601 of the feeding mechanism 6 are controlled to move to the location of the glue gun 3, and the scraping section held by the two second clamps 601 is used to scrape off the residual glue on the glue gun 3. After completing one scraping operation, the two second clamps 601 release the clamped scraping section, and the scraping section falls directly into the collection bucket below. For the next scraping operation, the first clamp 501 of the material pulling mechanism 5 is controlled to move to the first position near the positioning mechanism 4, clamp the movable end of the scraping tape 2, and move to the second position. The above operation can be repeated.

[0084] The characteristics and advantages of the scraping device of the present invention are:

[0085] 1. During the scraping process, the scraping device clamps a new scraping section each time for scraping, and there will be no residual glue left after repeated use of the scraping section, which effectively ensures the scraping effect and product quality.

[0086] 2. The scraping process of the scraping device can be completed automatically. There is no need to manually clean up the residual glue during the entire scraping process. The scraping state will not affect the normal operation of the equipment, saving costs and effectively improving production efficiency.

[0087] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
