Description

Technical Field

[0001] This utility model belongs to the technical field of scraper drilling machines, and more specifically, relates to a scraper for scraper drilling machines. Background Technology

[0002] Hot-fix rhinestones are common decorative items; their characteristic is that the front is a rhinestone facet composed of multiple facets as a decorative surface, while the back is a flat surface used to connect and fix the hot-fix rhinestone itself to the base.

[0003] In this process, hot-fix rhinestones require coating. After coating, the rhinestones are placed on a template and then scraped off using a rhinestone scraper. In existing technology, a scraper is used to scrape the rhinestones off the template. This scraper is typically a long, flat strip that scrapes the rhinestones off the template through its cross-section. However, this long scraper causes increased resistance on the flat surface during scraping, leading to rhinestone accumulation. Excessive accumulation increases the contact pressure between the scraper blade and the rhinestones, resulting in breakage. Furthermore, some template edges have slight curling, causing uneven flatness as the scraper passes over the template, resulting in poor scraping performance. Utility Model Content

Detailed Implementation

[0024] This application discloses a scraper for a drilling machine. Please refer to [link / reference]. Figures 1-3In a specific embodiment, the scraper 3 includes a blade 31, a cutting edge 32, and a second chamfer 33, all of which are integrally formed. The blade 31 has multiple segments, which are connected end-to-end and intersecting to form a sharp corner at the intersection of two blades 31. In this embodiment, at least two blade segments 31 intersect in an inverted V-shape, forming a sharp corner at the front end of the middle section of the blade 31. It should be noted that the front end of the blade 31 has at least one sharp corner, which faces the scraping surface of the template to be processed, thereby achieving a low-resistance scraping effect. The cutting edge 32 is located at the upper end of the blade 31, with one side facing the template to be processed. The cutting edge 32 is used for scraping and drilling the template, and it is integrally formed with the blade 31. A guide slope 321 is provided on the side of the blade 32 facing the incoming material direction. Two guide slopes 321 at the sharp corner meet to form a guide ridge. The guide ridge is inclined to guide the material to the sharp corner formed by the meeting of the two blades 32. Guide grooves 311 are provided on both end faces of the blade body 31. The guide grooves 311 on both sides of each sharp corner are not interconnected. The guide grooves 311 are located below the guide slope 321 to maintain a distance from the blade 32. A first chamfer 322 is provided on the back side of the guide slope 321 for each blade 32. A second chamfer 33 is provided at the middle sharp corner of the blade body 31 and the blade 32, and the second chamfer 33 is inclined at the upper end of the blade body 31 and smoothly transitions to the guide slope 321. The second chamfer 33 is the transition section at the junction of the blade 31 and the blade 32, so that the template with rolled edges abuts against the second chamfer 33 to form a transition, flatten it, and scrape off the hot rhinestones through the blade 32.

[0025] Specific Embodiment Two: Unlike Specific Embodiment One, the blade 31 of the scraper 3 is provided with four sections, which are connected end to end in an M-shape so that the front end of the blade 31 forms two sharp corners, and the blade 32 of the two sharp corners is provided with a second chamfer 33 at the connection point with the blade 31 so that the second chamfer 33 is aligned with the sharp corner of the blade 31.

[0026] This application also discloses a scraping drill; please refer to [link / reference needed]. Figures 4-5 The specific embodiment three includes the scraper and drilling chamber 2 of embodiment one or embodiment two.

[0027] Specifically, the scraping drill 1 includes a frame 11, a lifting mechanism 12, and a track 13. The drill collection chamber 2 is fixedly mounted on the frame 11 and located below the track 13. The lifting mechanism 12 is located at the lower end of the track 13 and is equipped with a slide rail that moves along the height direction, allowing the template to be processed to be moved along the height direction. The slide rail within the lifting mechanism 12 extends along the height direction to the lower end of the track 13. The track 13 is mounted on the upper end of the frame 11 and is rotatably connected to the inner sides of both ends of the frame 11. The track 13 transports the template lifted by the lifting mechanism 12 and has the ability to move horizontally, thus driving the template into the drill collection chamber 2 for scraping. The track 13 has multiple suction holes on its surface, and corresponding suction chambers are provided inside the track 13. The lower end face of each suction chamber has a connecting hole that communicates with the multiple suction holes. An air pump is installed on the outside of the track 13. The air pump's air intake is connected to the adsorption chamber installed inside the track 13, so that the template can be adsorbed by the air pump through the connecting hole and the adsorption hole.

[0028] The scraper 3 is installed at the lower end of the track 13, with its blade 32 facing the track and the blade 32 and the end face of the template that carries the hot drill located on the same horizontal plane. The moving direction of the track working surface is opposite to the direction of the sharp corner of the scraper 3, and in this embodiment, the template is drawn into the transport by suction using an air pump. The scraper 3 is located at the upper middle part of the drill collecting cavity 21 so that the hot drill scraped off by the scraper 3 falls into the drill collecting cavity 21. Auxiliary pressure rollers 23 are installed on both sides of the scraper 3 in the conveying direction to limit the height of the template. During operation, the template is suctioned by an air pump on the lower side of the track 13, causing the template to be adsorbed onto the lower side of the track 13 and move synchronously. At the same time, when the template passes through the auxiliary pressure rollers 23 on both sides of the scraper 3, the auxiliary pressure rollers 23 flatten and limit the template that enters the range of the scraper 3.

[0029] It should be noted that in this embodiment, the method of adsorbing the template by the track 13 can also be replaced by setting an electromagnet inside the track 13 that moves synchronously with the track 13, so that the template can be attracted by the electromagnet and move with the track 13.

[0030] Specifically, the drill collecting chamber 2 is installed at the lower middle of the track 13, located below the scraper 3, and is fixedly connected to both sides of the frame 11. The drill collecting chamber 2 includes a drill collecting cavity 21, a discharge port 22, an auxiliary pressure roller 23, and a support member 24. The drill collecting cavity 21 is installed below the scraper 3. The discharge port 22 is located on one side of the drill collecting cavity 21. The lower end of the drill collecting cavity 21 is inclined, and the bottom end of the inclined surface communicates with the discharge port 22 so that the hot drill can slide down to one end of the discharge port 22 through the inclined surface. There is a gap between the upper end of the drill collecting cavity 21 and the lower end of the track 13 to provide space for the template to pass through. Auxiliary pressure rollers 23 are installed on both sides of the drilling chamber 21 and are rotatably connected to both sides of the frame 11. The auxiliary pressure rollers 23 maintain a distance from the lower end face of the track 13, and this distance matches the thickness of the template, so as to assist in pressing the template entering the drilling chamber 21. The auxiliary pressure rollers 23 include a wheel body, a rotating shaft 231, a connecting plate 232, a spring 233, and a linkage rod. The rotating shafts 231 are respectively located on both sides of the wheel body, and extended linkage rods are provided at the lower ends of the rotating shafts 231 on both sides. Connecting plates 232 are fixedly installed on the linkage rods, and springs 233 are installed in the gap between the connecting plate 232 and the frame 11 to adjust the tightness of the pressure between the auxiliary pressure rollers 23 and the template. Multiple support members 24 are provided, and multiple support members 24 are mounted on the upper end of the drilling chamber 21, and the support members 24 are fixedly connected to the inner walls of both sides of the frame 11. The auxiliary pressure rollers 23 are installed on both sides of the scraper 3 in the material conveying direction to limit the height of the template by means of the auxiliary pressure rollers 23.

[0031] Working principle:

[0032] The scraping drill machine uses a scraping drill machine 1 and a support track 13 to transport the template to the drill collection chamber 2. The front end of the blade 31 of the scraper 3 forms a sharp corner, which is used to scrape the template with low resistance. The guide slope flattens the rolled edge of the template during the scraping process and scrapes off the hot drill through the blade. The guide grooves 311 on both sides of the blade 31 allow the hot drill to fall off more quickly after scraping. At the same time, the track 13 uses an air pump to adsorb the template in the adsorption chamber to ensure stable transportation. The lower end of the drill collection chamber 21 is inclined and connected to the discharge port 22 to guide and collect the scraped hot drill.

[0033] Specific Embodiment Four: Unlike Specific Embodiment Three, the scraper 3 is installed at the upper starting position of the track 13, with the blade 32 of the scraper 3 facing the track, and the blade 32 and the end face of the template carrying the hot-drill are on the same horizontal plane. The moving direction of the working surface of the track 13 is opposite to the direction of the sharp corner of the scraper 3. The drill collecting chamber 2 is always installed below the scraper 3 to collect the hot-drill scraped off by the scraper 3. Auxiliary pressure rollers 23 are installed on both sides of the scraper 3 in the conveying direction to limit the height of the template. During operation, the template is on the upper side of the track 13, connected to the air intake of an external air pump through an adsorption chamber inside the track 13. Air is drawn in by the air pump to adsorb the template onto the track 13, and the movement of the track 13 drives the template to move. Simultaneously, when the template passes the auxiliary pressure rollers 23 on both sides of the scraper 3, the auxiliary pressure rollers 23 flatten and limit the template entering the range of the scraper 3.
