Description

Technical Field

[0001] The invention relates to the technical field of flat bottom drill processing, in particular to a device for separating the front and back sides of a flat bottom drill. Background Art

[0002] Since the size of the lower end face of the flat-bottom drill is larger than that of the upper end face, a discharge operation is required during the polishing operation in the past. The discharge efficiency in this way is very low and the cost is high. For this reason, people have designed some equipment that can realize automatic discharge to assist the polishing operation of the flat-bottom drill, thereby improving the effect. Although this type of setting can realize automatic discharge, back-drilling is prone to occur during the discharge process. If these back-drills are polished together, not only will a large number of defective products be mixed in the finished material, but also the processing efficiency will be affected. Therefore, a technical solution that can solve the above problems is continued. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a flat bottom drill forward and reverse separation device which has a simple and reasonable structure, high production efficiency and can effectively pick out reverse drills.

[0005] A feeding device, arranged at one end of the frame;

[0006] A material transfer roller is rotatably arranged on a frame near the end of the feeding device and connected with the discharge end of the feeding device;

[0007] A material picking rod is rotatably arranged on a frame near the end of the feeding device, and is connected to the material transfer rod and the feeding belt, and is configured to pick up the drill and convey it to the feeding belt;

[0010] It is arranged on the frame and in contact with the surface of the top side of the picking rod, and is configured to scrape off the back drill picked out by the picking rod.

[0011] By applying glue on the surfaces of the picking rod and the feeding belt respectively in the above technical solution, the principle of the difference in adhesion caused by the difference in upper and lower areas of the flat-bottomed drill is effectively utilized to pick out the back-drilling during the loading process, thereby improving the quality of the finished product and the processing efficiency.

[0012] Furthermore, the second gluing device comprises:

[0013] A glue groove is arranged at the bottom of the frame and below the feeding belt;

[0014] A rubber roller, rotatably disposed at the bottom of the frame and located in the rubber groove, with its outer circumferential surface in contact with the outer surface of the feeding belt;

[0015] and a belt pressing roller, which can be rotatably arranged at the bottom of the frame and is located above the inner side of the feeding belt and is used to press the feeding belt toward the rubber rolling roller.

[0016] By applying glue to the feeding belt by means of glue rolling in the above further technical solution, the gluing efficiency is high and the glue is even, thereby further improving the processing quality.

[0017] Furthermore, the first gluing device comprises a gluing roller and a gluing cylinder;

[0018] The glue-applying roller can be rotatably mounted on the frame, and its outer circumference is in contact with the outer circumference of the material-picking roller away from the feeding belt;

[0019] The glue-applying cylinder is mounted above the frame, and a glue-out pipe is provided at the bottom thereof toward the space between the glue-applying roller and the material-picking roller.

[0020] The above further technical solution also adopts the method of rolling glue to apply glue to the material picking roller, which also effectively ensures the gluing speed and gluing uniformity.

[0021] Furthermore, the material picking roller has an interference fit with the material transferring roller and the gluing roller.

[0022] Furthermore, the scraper drill device is located on the top side of the material picking rod, close to the feeding device side and the upper side of the material picking rod to form an accommodating space.

[0023] Through the above further technical solution, the scraping drill device is arranged on one side of the material picking rod to form a accommodating space to accommodate the scraped back drills, so as to facilitate unified cleaning.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] During the feeding process, the flat-bottom drill forward and reverse separation device of the present invention utilizes the principle of the difference in adhesion caused by the difference in upper and lower areas of the flat-bottom drill to pick out the reverse drill during the feeding process, thereby avoiding the reverse drill from being mixed into the finished product. It not only effectively improves the processing efficiency, but also effectively improves the quality of the finished product.

[0035] Since the cross-section of the semi-finished flat-bottom drill 101 is a trapezoidal structure, its bottom area is larger than the top area, and glue is applied on the surfaces of the picking rod 5 and the feeding belt 3 respectively. During the feeding process, the flat-bottom drill 101 whose bottom surface is adhered to the feeding belt 3 will adhere to the feeding belt 3, and the flat-bottom drill 101 whose bottom surface is adhered to the picking rod 3 (i.e., the reverse drill) will adhere to the picking rod 5, thereby effectively utilizing the principle of the difference in adhesion caused by the difference in upper and lower areas of the flat-bottom drill 101 to pick out the reverse drill during the feeding process, thereby improving the quality of the finished product and the processing efficiency.

[0036] It is worth noting that the second gluing device includes a glue groove 6, a glue roller 7 and a belt pressing roller 8; the glue groove 6 is arranged at the bottom of the frame 1 and is located below the feeding belt 3; the glue roller 7 can be rotatably arranged at the bottom of the frame 1 and is located in the glue groove 6, and its outer cylindrical surface is in contact with the outer surface of the feeding belt 3; the belt pressing roller 8 can be rotatably arranged at the bottom of the frame 1 and is located above the inner side of the feeding belt 3 to press the feeding belt 3 toward the glue roller 7; glue is placed in the glue groove 6, and since the glue roller 7 is arranged in the glue groove and in contact with the glue, it is The surface of the feeding belt 3 is in contact with the feeding belt 3, and glue can be applied to the surface of the feeding belt 3 during its rolling process; the feeding belt is coated with glue by rolling glue, and the gluing efficiency is high and the glue is even, thereby further improving the processing quality; wherein, the glue rolling roller 7 and the belt pressing roller 8 are interference fit with the feeding belt 3, and due to their interference fit, the rotation of the glue rolling roller 7 and the belt pressing roller 8 can be driven by the feeding belt 3, or a driving mechanism can be set separately to drive them to rotate. When a driving mechanism is set separately, a motor and a pulley can be used to drive the two rollers to rotate synchronously with the feeding belt 3.

[0037] It should also be noted that the first gluing device includes a gluing roller 9 and a gluing cylinder 10; the gluing roller 9 can be rotatably mounted on the frame 1, and its outer cylindrical surface is in contact with the outer cylindrical surface of the picking roller 5 away from the feeding belt 3; the gluing cylinder 10 is mounted above the frame 1, and its bottom is provided with a glue outlet pipe 11 facing between the gluing roller 9 and the picking roller 5, the glue is placed on the gluing cylinder 10, and the glue is transported to the gluing roller 9 and the picking roller 5 through the glue outlet pipe 11 arranged at the bottom thereof, and under the action of the gluing roller 9 and the picking roller 5 rolling against each other, the glue can be applied to the surface of the picking roller 2; in order to facilitate the discharging of glue, a device for driving the glue to be smoothly discharged from the glue outlet pipe 11 can be arranged in the gluing cylinder 10, and the device can be a screw discharging device; in order to better gluing, a plurality of glue outlet pipes 11 can be arranged, which are evenly distributed along the axial direction of the gluing roller 9 and the picking roller 2; two or more gluing cylinders 10 can also be arranged.

[0038] In this embodiment, the feeding device 12 is a hopper, and the discharge end of the hopper extends to the upper side of the material transfer roller 4, and the flat bottom drill is delivered to the material selection roller. In some other embodiments, a conveyor belt is further provided between the hopper and the material transfer roller, and a limit bar is provided above the conveyor belt, so that the height of the limit bar and the conveyor belt allows only one flat bottom drill to pass through, thereby preventing the flat bottom drills from being stacked in multiple layers. The hopper first delivers the flat bottom drill to the conveyor belt, and then the conveyor belt delivers it to the material transfer roller 4.

[0039] In this embodiment, the surface of the material transfer rod 4 is interference fit with the surface of the material picking rod 5, the surface of the material picking rod 5 is interference fit with the surface of the feeding belt 3, and the surface of the gluing rod 9 is interference fit with the surface of the material picking rod 5; when the feeding belt 3 is running, the feeding belt 3 drives the material picking rod 5 to rotate, and then drives the material transfer rod 4 and the gluing rod 9 to rotate through the material picking rod 5; in some other embodiments, the material transfer rod 4, the material picking rod 5 and the gluing rod 9 are respectively provided with a driving mechanism for driving their respective rotations, and each driving mechanism drives them to rotate synchronously with the feeding belt 3. The driving mechanism can be a motor that drives each rod body to rotate through a pulley and a belt. When each rod body is provided with a driving mechanism, a certain gap can be set between them to facilitate the passage of the flat bottom drill.

[0040] In this embodiment, the scraper device is a scraper 18 fixedly mounted on the frame 1, which is located on the top side of the picking rod 5 close to the feeding device side, and is axially arranged along the picking rod 5 to form a accommodating space 16 on the upper side of the picking rod 5. One side of the scraper 15 is in contact with the surface of the picking rod 5. When the flat-bottom drill 101 attached to the surface of the picking rod 5 rotates to the scraper 15, it stays in the accommodating space 16 under the blocking action of the scraper 18. When the flat-bottom drill 101 in the accommodating space 16 is full, it can be removed manually.

[0041] In this embodiment, the feeding belt 3 is made of rubber material; the outer layers of the material picking rod 5 and the material transfer rod 4 are both rubber layers. When feeding, the flat-bottom drill 101 can squeeze the rubber layer to enable the flat-bottom drill 101 to smoothly pass through the gap between the material picking rod 5 and the material transfer rod 4 and through the gap between the material picking rod 5 and the feeding belt 3. In actual application, the flat-bottom drill 101 is placed in the hopper, and the hopper conveys the flat-bottom drill 101 to the surface of the transfer roller 4. At this time, the large end faces of most of the flat-bottom drills 101 are in contact with the surface of the transfer roller 4, and the small end faces of a small part of the reverse drills 102 generated during the conveying process and some defective drills are in contact with the surface of the transfer roller 4. After the transfer roller 4 rotates, the flat-bottom drill 101 is conveyed to the surface of the picking roller 5. Since the picking roller 5 is coated with glue, the flat-bottom drill 101 is attached to the surface of the picking roller 5. At this time, the small end faces of most of the flat-bottom drills 101 are in contact with the surface of the picking roller 5, and the large end faces of a small part of the reverse drills 102 are in contact with the surface of the picking roller 5. After the picking roller 5 rotates, the flat-bottom drill 101 is conveyed to the surface of the feeding belt 3. Since the surface of the feeding belt 3 is also coated with glue, the area of ​​the large end face is larger than the area of ​​the small end face, and the area adhesion of the large end face is stronger than the adhesion of the small end face. The surface of the picking rod 5 and the surface of the feeding belt 3 coated with glue are touched, and the flat bottom drill 101 is attached to the contact side of the large end face, that is, after the picking rod 5 rotates, the small end face of most of the flat bottom drills 101 contacts the surface of the picking rod 5, and the large end face contacts the surface of the feeding belt 3, and the large end face of a small part of the reverse drill 102 contacts the surface of the picking rod 5, and the small end face contacts the surface of the feeding belt 3. Under the action of the adhesion difference, most of the flat bottom drills 101 are attached to the surface of the feeding belt 3 through the large end face and are transported by the feeding belt 3 to the polishing machine to polish the small end face of the flat bottom drill 101. A small part of the reverse drill 102 rolls with the picking rod 5 to the scraper 15, stays in the accommodating space 16 under the action of the scraper 18, and is finally removed manually. Through the above process, the flat bottom drill 101 is loaded and most of the reverse drill 102 is picked out at the same time, thereby improving the processing quality and processing efficiency.

[0042] In some embodiments, the polishing device for polishing the flat bottom drill is generally arranged above the feeding belt of the frame, and a drill scraper for scraping the finished drill is arranged at the end of the frame.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
