Description

Technical Field

[0001] This utility model belongs to the technical field of scraper drilling machines, and more specifically, relates to a scraper drilling machine with air suction. 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] Hot-fix rhinestones require coating, which is only applied to the front (decorative surface). The rhinestones are typically adhered to a template before coating; after coating, the rhinestones adhering to the template need to be scraped off and collected. For example, a hot-fix rhinestone template scraping machine (patent number CN202222173566.7) uses a conveyor belt and rollers to transport the template to the scraper position for rhinestone scraping. However, if the gap between the two rollers is too large during transport, the template will be uneven, making scraping difficult; if the gap is too small, the rhinestones will be crushed by the rollers. Utility Model Content

[0004] This utility model provides a drill scraper equipped with air suction, which can achieve more efficient and stable transport of hot-drill templates and ensure uniform force on the transport template and the drill scraper.

[0005] This utility model discloses a scraper drill with suction, comprising a track and an air pump. One side of the scraper drill has a feeding port for supporting the lifting and lowering of the template to be processed, feeding it into the track. The track is located on the upper side of the scraper drill, is U-shaped, and is driven to rotate by external force. The surface of the track is evenly provided with several suction holes. Both sides of the track are enclosed by cover plates to form a suction chamber inside the track. The suction chamber and the suction holes are kept in communication. The air pump is fixedly installed on the scraper drill. The air pump's suction port is connected to an air vent on the cover plate to draw air from the suction chamber to create low pressure. During operation, the track rotates, the template to be processed is placed on the track surface, and the air pump draws air to create low pressure in the suction chamber. The external atmospheric pressure then forces the template to be processed to deform towards the track surface, causing the template to adhere to the track and remain flat.

[0006] As a further improvement of this utility model, the adsorption chamber includes several independent chambers, all of which are connected to the air intake of the air pump; each chamber is connected to the adsorption hole corresponding to the track surface; during operation, at least one chamber adsorbs the template.

[0007] As a further improvement of this utility model, it also includes a lifting mechanism, which is installed on one side of the scraper drill and is used to adjust the position of the template along the height direction to ensure that the template is flush with the contact surface of the track. The lifting mechanism includes a first motor, a main chain and a lifting slide rail. The main chain is driven by the first motor to move the placement plate along the lifting slide rail to adjust the height position of the template.

[0008] As a further improvement of this utility model, it also includes a scraper, which is fixedly disposed on the underside of the track, and the scraper maintains a distance from the lower end face of the track. The scraper is used to scrape off the hot-fix rhinestones on the template.

[0009] As a further improvement of this utility model, the scraper is a flat scraper, which is composed of a blade, and the side of the blade facing the template to be processed is the cutting edge; the width of the scraper is matched with the width of the track, and the distance between the scraper and the track is matched with the height of the template.

[0010] As a further improvement of this utility model, the scraper is a scraper blade, which is composed of multiple blade sections that are connected end to end and arranged in a cross pattern; the intersection of two blade sections forms a sharp corner; the side of the blade facing the template to be processed is the cutting edge, and the side of the cutting edge facing the material feeding direction is provided with a guide slope; the two guide slopes of the sharp corner meet here to form a guide ridge, and the guide ridge is inclined to guide the material to the sharp corner formed by the intersection of the two corresponding cutting edges; the distance between the scraper blade and the track is matched with the height of the template.

[0011] As a further improvement of this utility model, guide grooves are provided on both sides of the sharp corner; the guide grooves on both sides of each sharp corner are not interconnected; the guide grooves are located on the lower side of the guide slope to maintain a distance from the blade.

[0012] As a further improvement of this utility model, air outlets are provided on both sides of the upper end of the drilling machine. The air outlets are connected to the air outlets of the air pump through a hose, so as to blow away the hot-fix rhinestones remaining on the scraper and / or the hot-fix rhinestones on the back of the template after drilling.

[0013] As a further improvement of this utility model, it also includes a pressure roller, which is installed in the scraping and drilling mechanism. The pressure roller is flush with the scraper and is arranged on both sides of the scraper along the feeding direction. The two sides of the pressure roller are movably connected to the scraping and drilling machine.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By creating low pressure within the adsorption chamber using an air pump, and then utilizing the adsorption holes to allow external atmospheric pressure to compress the template tightly against the track surface, the problem of uneven templates or crushed hot-hot drills caused by wheel gaps in traditional roller transport is solved. The interconnected design of the adsorption chamber and adsorption holes ensures uniform contact between the template and the track, making the transport process more efficient and stable, reducing hot-hot drill breakage and defective product residue, and improving the yield of scraped drills.

Detailed Implementation

[0021] Specific Implementation Example 1: Please refer to... Figs. 1-3 A scraping drill with suction capability includes a track 2, a lifting mechanism 3, a track drive mechanism 4, an air pump 5, and a scraping mechanism 6. The track 2 is located at the upper end of the scraping drill 1 and is used to transport the hot-drill template. The lifting mechanism 3 is installed on one side of the scraping drill 1 and is used to move the hot-drill template along the height direction. The track drive mechanism 4 is installed on one side of the upper end of the scraping drill 1 and is used to drive the track 2 for operation. The air pump 5 is installed on one side of the upper end of the scraping drill 1, and the output end of the air pump 5 is connected to the inside of the track 2 via a hose. The scraping mechanism 6 is installed at the lower end of the track to scrape the hot-drill template from the template into the scraping mechanism 6.

[0022] Specifically, the scraping drill 1 includes a frame 11, a first housing 12, and a second housing 13. A track 2 is mounted on the frame 11 and rotatably connected to the upper end of the frame 11. A blower 111 is provided through one side of the frame 11 to blow away the hot drill inside the blower 111 via an external air pump. Upper frames 112 are provided on both sides of the upper end of the frame 11 and are fixedly connected to the frame 11, allowing the track drive mechanism 4 and the air pump 5 to be placed on the upper frames 112. A pressure wheel 113 is provided at the lower end of the track 2, and both ends of the pressure wheel 113 are rotatably connected to the frame 11. There is a gap between the pressure wheel 113 and the track 2, allowing the template to be driven by the track 2, and the pressure wheel 113 assists in pressing and limiting the template at the scraping drill mechanism 6. The first box 12 and the second box 13 are disposed between the two side frames 11, and are arranged side by side. The first box 12 and the second box 13 are fixedly connected to the inner side of the two side frames 11. The first box 12 and the second box 13 are installed inside the track 2. The lower end face of the first box 12 has a plurality of first suction holes 121, which are evenly arranged. The first box 12 has a first air inlet 122 that extends through one side of the frame 11. The first air inlet 122 is interconnected with the first box 12 and is connected to the output end of the air pump 5 through a flexible hose, so that the output end of the air pump 5 can draw air into the first box 12. The lower end face of the second box 13 has a plurality of second suction holes 131, which are evenly arranged. The second housing 13 has a second air inlet 132 extending through one side of the frame 11. The second air inlet 132 is interconnected with the second housing 13, and a flexible hose connects the second air inlet 132 to the output end of the air pump 5, allowing the output end of the air pump 5 to draw air into the second housing 13. It should be noted that the width or length of the template may vary and may be larger than the area of ​​a single adsorption chamber. Therefore, two adsorption chambers are provided for easy adjustment to ensure the template can be adsorbed onto the track 2. The first housing 12 contains a first adsorption chamber, forming a separate chamber within the track 2. The second housing 13 contains a second adsorption chamber, forming a separate chamber within the track 2. The first housing 12 and the second housing 13 are not interconnected. The first adsorption hole 121 connects the first adsorption chamber to the outside, and the second adsorption hole 131 connects the second adsorption chamber to the outside.

[0023] Specifically, the track 2 includes a track, suction holes 21, a track cavity 22, and track wheels 23. The track is arranged around the track wheels 23, and multiple uniformly spaced suction holes 21 are formed through the track surface. A cavity is formed within the inner layer of the track around the track wheels 23; this cavity is the track cavity 22. The first housing 12 and the second housing 13 are both installed within the track cavity 22, and the first suction holes 121 and the second suction holes 131 always face downwards, so that air is simultaneously drawn through the suction holes 21 when air is drawn into the first housing 12 and the second housing 13. It should be noted that the lower end of the corresponding range of the multiple first suction holes 121 and the multiple second suction holes 131 constitutes the corresponding air-drawing range of the track. Track wheels 23 are installed at both ends of the track wheels 22, and the track wheels 23 at both ends are rotatably connected to the frame 11. One end of the track wheel 23 is connected to the output end of the track drive mechanism 4, so that the track wheel 23 is driven to rotate and the track moves by the track drive mechanism 4.

[0024] Specifically, the lifting mechanism 3 is installed at the lower end of the track 2. The lifting mechanism 3 includes a mounting plate, a first motor 31, a main chain 32, a driven chain 33, and a lifting slide rail 34. The first motor 31 is installed at the lower end of the frame 11, and one end of the main chain 32 is sleeved on the output end of the first motor 31 so that the main chain 32 can be driven to rotate by the first motor 31. The other end of the main chain 32 is sleeved with a connecting rod. The driven chains 33 are respectively sleeved on both sides of the connecting rod and arranged along the height direction. The other end of the driven chain 33 away from the connecting rod is connected to a rotating shaft so that when the main chain 32 rotates, it drives the connecting rod and the driven chain 33 to rotate synchronously. The chain 33 is slidably connected to the lifting slide rail 34, which is located on the side wall of the frame 11. The shelf is installed at the connection point of the chain 33 and the lifting slide rail 34. When the main chain 31 rotates, the chain 33 rotates around the connecting rod and the pivot along the height direction, so as to realize that the shelf installed at the end of the lifting slide rail 34 moves along the opening direction of the lifting slide rail 34.

[0025] Specifically, the track drive mechanism 4 includes a second motor 41, a track drive chamber 42, and an output shaft 43. The second motor 41 is mounted on the upper frame 112 and is fixedly connected to the upper frame 112. One end of the track drive chamber 42 covers the output end of the second motor 41, and the other end covers one end of the track wheel 23. One end of the output shaft 43 is fixedly connected to the axis of the track wheel 23, so that the rotation of the output shaft 43 drives the track wheel 23 to rotate. The other end of the output shaft 43 is connected to an output chain 431, and the other end of the output chain 431 is connected to the output chain of the second motor 41, so that the output chain 431 is driven to rotate by the output end of the second motor 41, thereby driving the track wheel 23 to rotate.

[0026] Specifically, the air pump is mounted on the upper frame 112, and one end of the air pump is provided with an output port 51, which has multiple output ports 51. In this embodiment, there are two output ports 51, which are respectively connected to the first air inlet 122 and the second air inlet 132 via flexible hoses, so as to achieve air intake from the first housing 12 and the second housing 13 through the air pump. During operation, the air pump 5 draws air to create a low pressure in the first housing 12 and the second housing 13, and uses the external atmospheric pressure to compress the template to be processed towards the surface of the track 2, so that the template to be processed fits against the track 2 to keep it flat.

[0027] Specifically, the drilling mechanism 6 includes a drill storage bin 61 and a scraper 62. The drill storage bin 61 is installed at the lower end of the track 2 and is covered by the periphery of the pressure roller 113. One end of the drill storage bin 61 has an opening for storing and removing scraped hot-drilling material. The scraper 62 is installed at the upper middle part of the drill storage bin 61. Both ends of the scraper 62 are fixedly connected to the frame 11, and the scraper 62 maintains a distance from the lower end face of the track 2. This distance matches the protrusion height of the hot-drilling material on the template, so that the scraper 62 can scrape the template adsorbed on the track 2. In this embodiment, the scraper 62 is a flat scraper, which consists of a blade. The side of the blade facing the template to be processed is the cutting edge, and the width of the scraper 62 matches the width of the track. In this embodiment, the scraper 62 is installed at the lower end of the track 2 and at the upper end of the drill storage chamber 61, so that the scraped hot drill can fall directly into the drill storage chamber 61, effectively solving the problem of hot drill accumulation.

[0028] Working Principle: The scraping drill maker 1 is connected to the air pump 5 via the first housing 12 and the second housing 13 within the scraping drill maker 1. The air pump 5 draws air into the adsorption chamber, causing the airflow to pass through the first adsorption hole 121, the second adsorption hole 131, and the adsorption holes 21 on the surface of the track 2, stably adsorbing the hot-drill template during transportation onto the track 2. Since the width or length of the template may vary and may be larger than the area of ​​a single adsorption chamber, two adsorption chambers are provided for easy adjustment to ensure the template is held firmly on the track 2. The track 2 is driven by the track drive mechanism 4 to continuously transport the template. Simultaneously, the scraper 62 of the scraping drill mechanism 6 maintains a preset distance from the lower end face of the track 2, scraping away any defective hot-drills from the template. The adsorption effect ensures the template is transported smoothly, improving the yield of scraped drill finished products.

[0029] Specific Embodiment Two: Unlike Specific Embodiment One, both sides of the track 2 are enclosed by cover plates, so that the adsorption cavity formed inside the track 2 contains only a single independent chamber. Each independent chamber is connected to the adsorption hole 21, allowing it to be matched and adsorbed with templates of different lengths. Each independent chamber is connected to the air intake of the air pump 5, and each independent chamber is connected to the corresponding adsorption hole 21 on the surface of the track 2, ensuring that the chamber adsorbs the template accordingly.

[0030] Specific Embodiment Three: Unlike Specific Embodiment One, the scraper 62 is composed of multiple blade sections connected end-to-end and arranged in a crisscross pattern; a sharp corner is formed at the intersection of two blade sections; the side of the blade facing the template to be processed is the cutting edge, and a guide ramp is provided on the side of the cutting edge facing the material inflow direction; the two guide ramps at the sharp corner meet here to form a guide ridge, which is inclined to guide the material to the sharp corner formed by the intersection of the two corresponding cutting edges; the distance between the scraper 62 and the track 2 matches the height of the template. Guide grooves are provided on both sides of the sharp corner; the guide grooves on both sides of each sharp corner are not interconnected; the guide grooves are located below the guide ramps to maintain a distance from the cutting edge. In this embodiment, the sharp-angled scraper scrapes off the hot-fix rhinestones on the template by facing the template to be processed. The sharp-angled scraper reduces the resistance of scraping the rhinestones and improves the efficiency of scraping.
