[0002] At present, there is no automatic hair implanting equipment for copper-free pointed filament hair implanting in the market. The mainstream method is manual hair implanting. For the rest of the pointed filament hair implanting, it is for copper toothbrushes. The production equipment uses a bobbin to move back and forth in a shuttle case for wire drawing, continuously sending the toothbrush filaments into the hair implanting nozzle, and then driving the aluminum sheet feeding mechanism by a cam mechanism to send the aluminum sheet into the slicing knife box for slicing, and then implanting it into each hole of the toothbrush head together with each bundle of toothbrush filaments in sequence. Different colored toothbrush filaments are implanted according to the programmed setting. The copper automatic equipment has relatively low efficiency. At the same time, defective products will cause the entire toothbrush to be scrapped, increasing the production cost. For toothbrushes with different toothbrush filaments, the production process will be more complex, restricting the quantity, length, color, and shape of the blank materials for a single toothbrush head. The types of toothbrushes that can be produced are few, and the hair implanting density is relatively low. Summary of the Invention

Each time the disk rotates one circle, it brushes a certain amount of hair filaments from the shuttle shell of the hair holding flow channel 43. Workers put the toothbrush wires cut to a fixed length into the shuttle shell and press the toothbrush wires with a long-stroke pen rod cylinder. As the toothbrush wires in the shuttle shell decrease, the cylinder also gradually retracts, always driving the pressing mechanism to press the toothbrush wires. When feeding is required, as long as the worker presses the manual pressing valve, the cylinder can be easily pulled open, and the toothbrush wires can be put into the shuttle shell. There is a toothbrush wire flattening mechanism above the shuttle shell to pat the toothbrush wires flat. The number of shuttle shells is determined by the number of types of toothbrush wires required for the toothbrush head; The 400W servo motor drives the synchronous wheel set and the material tray to rotate one circle, and the toothbrush filaments are brushed from the bobbin case. There is a baffle of the same thickness outside the circumference of the material tray, so that the toothbrush filaments taken by the material tray will not be missed.

The number of holes on the material tray corresponds to the number and type of holes on the toothbrush head. When changing products, you only need to replace the corresponding material tray. The synchronous pulley must have enough meshing teeth with the synchronous belt. After the brushing disc brushes the toothbrush filaments, the toothbrush filament suction mechanism moves forward to the top of the toothbrush filaments, and the lifting cylinder moves down to cover each bundle of toothbrush filaments in the material taking tube, which is sucked away by the vacuum system.

First, it blows to detect whether the brush head is air-leaking, and then the blanking module performs blanking.

[0018] Working principle: As Figures 1-6As shown in the figure, the turntable mechanism 1 is driven by the motor 12 to rotate the divider 11 to drive the carrier module to displace. The carrier module tooling 13 is composed of a carrier workpiece, a first slide rail mechanism 131, a clamping and fixing device 132, a deburring workpiece 133, a limiting workpiece 134 and a positioning bushing 135. The carrier can slide up and down. During brush piece feeding, hot cutting, and hot ironing, the carrier is on the upper side and is fixed by the clamping and fixing device 132. During hair implanting, the carrier is on the lower side and is positioned by the limiting workpiece 134. When cooperating with other workstations, it is assisted in positioning by the positioning bushing 135. At the upper end of the brush filament implanting mechanism 2 are two mounting plates for inserting anti-static tubes, with two integrated brush filament implanting die plates 21 connected in the middle. Above is installed a waste blowing and cleaning mechanism 22, and below is a die plate with a hole shape to prevent the toothbrush head hole shape. Guide post positioning cylinders 23 are installed on both sides. During operation, the die plate is pushed by the cylinder to fit the brush filament workpiece at the brush filament work station. The brush filaments are integrated into the brush filament workpiece through the holes in the die plate. The anti-static tubes are connected to the brush filament picking mechanism 4 and the brush filament implanting mechanism. At the front end of the brush filament pushing mechanism are two sets of brush filament push rods. The brush filament push rod guide plate assists in preventing the push rods from breaking. Guide post positioning cylinders 23 are installed on both sides to correct the workstation position. The displacement cylinder makes the brush filament push rod workstation fit the brush filament workstation. The first servo motor 31 of the brush filament pushing mechanism moves the brush filament push rod forward to push the brush filaments in the brush filament workpiece into the carrier. The sheet material auxiliary pressing mechanism 32 presses the sheet material. The hair blocking cylinder 33 prevents the hair from being pushed off. After pushing the hair, the lifting cylinder ejects the carrier. At this time, most of the hair bundle is exposed outside and is easily dropped. The hair pushing assembly 35 pushes the hair back into the carrier, assisted by the hair blocking workpiece. On the back of the brush filament picking mechanism 4 is a synchronous rotation mechanism 45 composed of a servo, a reducer, and a synchronous pulley and synchronous belt. At the top of each synchronous pulley is installed a brush filament disc 42. There are a certain number of semi-circular holes of different sizes on the circumference of the brush filament disc 42. The brush filament disc is in interference fit with the surrounding baffles. Each time the disc rotates one circle, a certain amount of hair filaments are brushed from the shuttle shell of the hair storage channel 43. The operator puts the cut-to-length toothbrush filaments into the shuttle shell and presses the toothbrush filaments with a long-stroke pen rod cylinder. As the toothbrush filaments in the shuttle shell decrease, the cylinder will gradually retract, always driving the pressing mechanism to press the toothbrush filaments. When feeding is required, the operator can easily pull the cylinder open by pressing the manual pressing valve and put the toothbrush filaments into the shuttle shell. There is a toothbrush filament leveling mechanism above the shuttle shell to pat the toothbrush filaments flat. The number of shuttle shells is determined by the number of types of toothbrush filaments required for the toothbrush head; The 400W servo motor drives the synchronous wheel set and the material tray to rotate one circle, and the toothbrush filaments are brushed from the bobbin case. There is a baffle of the same thickness outside the circumference of the material tray, so that the toothbrush filaments taken by the material tray will not be missed. The circumference diameter of the material tray and the baffle is the same. The material tray uses a positive tolerance of 0.05-0.08MM. There are different numbers of material extraction holes on the material tray. The central angle of the material extraction hole is about 240°, and the diameter size is calculated according to the number of toothbrush filaments required on the toothbrush head. The number of holes on the material extraction tray corresponds to the number and type of holes on the toothbrush head. When changing products, you only need to replace the corresponding material extraction tray, and the synchronous pulley must be aligned with the synchronous belt There are enough meshing teeth. After the brush disc picks up the toothbrush filaments, the toothbrush filament suction mechanism moves forward to the top of the toothbrush filaments, the lifting cylinder moves down, and each bundle of toothbrush filaments is covered in the material taking tube, which is sucked away by the vacuum system. The cylinder returns to the origin. There are two types of inner diameters of the material taking tube, φ3.0mm and φ2.5mm. The sheet material feeding mechanism is fed by the vibration plate 51, and the straight vibration flow channel 54 stores the material. The photoelectric detection mechanism 52 detects full material. The second servo motor 53 drives the KK module to divide the brush sheet into different positions. The power is turned off to detect whether there is sheet material in the fixed groove. The flip loading mechanism is pushed into the exposed hair in the hair storage workpiece by the hair trimming cylinder 61, and the hair trimming is completed. The avoidance cylinder descends to make way, the rotating cylinder 65 flips the clamping mechanism 63, the loading displacement cylinder 64 pushes the clamping mechanism 63 into the carrier to install the sheet material, and the positioning cylinder is also inserted into the positioning hole of the carrier. The up and down displacement cylinder 66 descends to move the carrier to the hair planting position. The hot cutting mechanism 7 is controlled by the cylinder carrier mechanism 74 to control the lifting and displacement of the hot cutting module 71. The thermostat controls the temperature of the heating core at 900℃. The first hair pushing module 72 and the hair blocking module 73 shape the brush wire, and the hot cutting knife cuts off the excess length. The hot blanching mechanism 8 is blocked by the second hair pushing module 82 to prevent the hair shape from being messed up during hot blanching. , the edge protection clamp 81 protects the brush piece to prevent the melted plastic from overflowing during hot stamping. The 800W high-power heating core is used to quickly heat the welding head to 900 degrees Celsius, and the upper surface of the toothbrush piece and the toothbrush wire are quickly melted and welded with high temperature. The temperature is stabilized within 900℃ by the intelligent temperature controller. The fixed workpiece above the welding head is cooled by water. The KK module is set with three working positions, a high-speed moving position, a medium-speed moving position, and a slow moving position when approaching the product. The unloading mechanism 9 is composed of an unloading clamp module 91 and an air blowing detection module 92. First, air is blown to detect whether the brush head is leaking, and then the unloading module unloads; After the toothbrush filaments are manually put in, the feeding tray automatically picks up the toothbrush filaments, and sucks them into the anti-static tube by vacuum extraction. The core mechanism integrates the toothbrush filaments and pushes them into the holes of the toothbrush piece. After shaping, the roots of the bristles are finally welded to the toothbrush head piece by high-temperature sol. The bristles treated with hot-melt technology will be very stable when cooled down, and the bristles will not fall off easily.
