Description

Technical Field

[0001] This application relates to the technical field of brush production, and particularly relates to an automatic brush production device. Background Art

[0002] A brush is a common cleaning tool, usually composed of a handle and bristles. The bristles can be made of various materials, such as animal hairs (such as pig bristles, horse hairs), synthetic fibers (such as nylon, polypropylene), natural fibers (such as bamboo, plant fibers), etc. During the production process of a brush, the bristles need to be first stuffed into an iron sheet, and then bonded together at the connection end between the bristles and the iron sheet with glue.

[0003] During the production process of a brush, first, the bristles are stuffed into an iron sheet, then bonded together at the connection end between the bristles and the iron sheet with glue. Next, the iron sheet with bristles is sleeved on the handle and fixed with nails. Finally, the completed handle is packed into a box. In order to improve the production efficiency of brushes, an automatic brush production device is needed. Summary of the Invention

[0004] The purpose of this application is to provide an automatic brush production device to improve the production efficiency of brushes.

[0005] An automatic brush production device provided by this application adopts the following technical solution: It includes a bristle conveyor rack, a handle feeding device, a nail - fixing and handle - installing device, and a box screening device. The bristle conveyor rack is connected with a glue - filling device and a glue - shaking device. The bristle conveyor rack is slidably connected with a placement box. The bristle conveyor rack is connected with a transmission mechanism for driving the placement box to pass through the glue - filling device and the glue - shaking device in sequence. The nail - fixing and handle - installing device is used to fixedly connect the iron sheet on the bristle conveyor rack with the handle on the handle feeding device and move it to the box screening device.

[0006] By adopting the above - mentioned technical solution, the iron sheets with installed bristles are neatly placed on the placement box. The transmission mechanism drives the placement box to pass through the glue - filling device and the glue - shaking device in sequence. The glue - filling device fills glue at the connection between the iron sheet and the bristles, realizing automatic glue - filling and improving the efficiency of glue - filling. The glue - shaking device drives the placement box to shake, dispersing the glue in the bristles and improving the adhesion effect between the bristles and between the bristles and the iron sheet. The handle feeding device moves the handle to the nail - fixing and handle - installing device, and the handle and the iron sheet are automatically fixedly connected through the nail - fixing and handle - installing device, reducing manual operation and improving the assembly accuracy and speed. The entire production process from bristle processing to handle assembly and then to box screening is an integrated design, significantly reducing production costs and improving production efficiency.

[0007] Optionally, the bristle conveying rack is connected with a first lifting assembly for driving the placement box to lift. The glue filling device includes a glue filling applicator slidably connected to the bristle conveying rack, a glue conveying pipe connected to the glue filling applicator, and a first driving assembly for driving the glue filling applicator to slide in the directions of the X-axis, Y-axis, and Z-axis. The first driving assembly is connected to the bristle conveying rack.

[0008] By adopting the above technical solution, when the placement box moves to the first lifting assembly, the first lifting assembly drives the placement box to lift, so that the placement box is separated from the transmission mechanism. The first driving assembly drives the glue filling applicator to move in the directions of the X-axis, Y-axis, and Z-axis, so that the glue filling applicator is inserted into the bristles of different iron sheets in sequence, injects glue into them, and adheres the connection between the bristles and the iron sheet, realizing automatic glue filling and improving the efficiency of the overall glue filling of the brush.

[0009] Optionally, the glue shaking device includes a second lifting assembly for driving the placement box to lift, a rotating plate rotatably connected to the bristle conveying rack, a first driving member for driving the rotating plate to rotate, and a clamping mechanism connected to the rotating plate. The second lifting assembly is connected to the bristle conveying rack, the first driving member is connected to the bristle conveying rack, and the clamping mechanism is used for clamping the placement box.

[0010] By adopting the above technical solution, when the bristles after glue filling move to the second lifting assembly, the second lifting assembly drives the placement box to lift, so that the placement box is separated from the transmission mechanism. The clamping mechanism clamps the placement box, and the first driving member drives the rotating plate to rotate, that is, the placement box swings, so that the glue in the bristles is dispersed, improving the adhesion effect between the bristles and between the bristles and the iron sheet.

[0011] Optionally, the clamping mechanism includes two clamping plates slidably connected to the rotating plate and a linkage assembly for driving the two clamping plates to slide in the directions of approaching or separating from each other. The linkage assembly is connected to the rotating plate, and support plates are connected to the opposite sides of the two clamping plates.

[0012] By adopting the above technical solution, the linkage assembly drives the two clamping plates to slide in the directions of approaching or separating from each other, so as to realize clamping or releasing of the placement box by the two clamping plates. Before the two clamping plates clamp the placement box, the two support plates first support the placement box, and then the two clamping plates clamp it, improving the stability of the placement box being clamped.

[0013] Optionally, the linkage assembly includes a clamping cylinder connected to one of the clamping plates and four limit blocks connected to the rotating plate. The output end of the clamping cylinder is connected to the other clamping plate. One clamping plate corresponds to two limit blocks, and the clamping plate is located between the two limit blocks.

[0014] By adopting the above technical solution, when the output end of the clamping cylinder extends, one of the clamping plates first abuts against one of the limit blocks, causing the other clamping plate to move away from this clamping plate, that is, the two clamping plates move away from each other, realizing the release of the placement box by the two clamping plates. The two limit blocks farthest apart play a role in restricting the sliding of the clamping plates, preventing the clamping plates from disengaging from the rotating plate during the sliding process. When the output end of the clamping cylinder shortens, one of the clamping plates first abuts against one of the limit blocks, causing the other clamping plate to move towards this clamping plate, that is, the two clamping plates move towards each other, realizing the clamping of the placement box by the two clamping plates.

[0015] Optionally, the handle feeding device includes a feeding frame and a clamping mechanism. The clamping mechanism is located on one side of the feeding frame. The feeding frame is connected with a vibrating disk. The discharging end of the vibrating disk is connected with a discharging component. The feeding frame is connected with a fixing component. The feeding frame is slidably connected with a receiving plate. The fixing component is located between the receiving plate and the discharging component. The receiving plate is spacedly connected with a plurality of receiving rods. The feeding frame is connected with a second driving component for driving the receiving plate to slide towards or away from the clamping mechanism. The clamping mechanism is used to drive the handle on the receiving plate to move to the nail attaching handle device.

[0016] By adopting the above technical solution, the handles in the vibrating disk pass through the discharging component and the fixing component in sequence through the vibrating disk and are suspended on two adjacent receiving rods. At this time, the fixing component fixes the handle between the discharging component and the receiving plate, preventing the handle from continuing to move towards the receiving rod. The second driving component drives the receiving plate to slide towards the clamping mechanism, so that the other two receiving rods correspond to the discharging component. The fixing component releases the handle, enabling the handle to move onto the receiving plate. When the receiving plate is full of handles, the fixing component fixes the handle between the discharging component and the receiving plate again. The second driving component continues to drive the receiving plate to slide towards the clamping mechanism, causing each handle on the receiving plate to be staggered from the discharging component, thus facilitating the clamping mechanism to drive the handle on the receiving plate to move to the nail attaching handle device, realizing the automatic feeding of the handle and improving the efficiency.

[0017] Optionally, the feeding frame is connected with a bracket corresponding to the discharging component. The bracket is connected with a sensor for sensing the handle on the receiving plate.

[0018] By adopting the above technical solution, when the sensor senses the handle on the receiving plate, the fixing component fixes the handle. Subsequently, the driving component drives the receiving plate to slide towards the clamping mechanism, so that the other two receiving rods correspond to the discharging component, accelerating the production rhythm and improving the overall production efficiency.

[0019] Optionally, the bracket includes a vertical plate connected to the feeding rack and two horizontal plates connected to the vertical plate. The receiving rod is located between the two horizontal plates. The sensor is a transmissive photoelectric sensor. The emitter of the sensor is connected to one of the horizontal plates, and the light receiver of the sensor is connected to the other horizontal plate. The emitter of the sensor corresponds to the light receiver of the sensor. The receiving plate is provided with an avoidance hole, and both the emitter of the sensor and the light receiver of the sensor correspond to the avoidance hole. The receiving rod is located between the avoidance hole and the vibrating bowl.

[0020] By adopting the above technical solution, the transmissive photoelectric sensor has high detection accuracy and extremely short response time, and can quickly detect the movement of the handle to the receiving plate. When the handle moves to the receiving plate, the horizontal plate farthest from the feeding rack restricts the movement of the handle in the direction close to the horizontal plate, thereby improving the stability of the handle hanging on the receiving rod.

[0021] Optionally, the box screening device includes a controller, a transmission rack and a grasping mechanism. The transmission rack is connected with a first baffle and at least two measurement detectors with different heights. The transmission rack is connected with a transmission component, and the transmission component is used to drive the installation box to pass through each measurement detector and move to the first baffle. The grasping mechanism is located on one side of the first baffle, and each measurement detector and the grasping mechanism are electrically connected to the controller.

[0022] By adopting the above technical solution, after the installation box is filled with brushes, it moves to the transmission component, and the transmission component drives the installation box to slide towards the direction close to the first baffle. The installation box passes through each measurement detector during the movement. The controller can judge the size of the installation box according to the number of measurement detectors that detect the installation box. Until the installation box abuts against the first baffle, the grasping mechanism grabs the installation box and places it in the corresponding area. The system realizes automation, reduces manual intervention, improves efficiency and is relatively convenient.

[0023] Optionally, the grasping mechanism includes a first robotic arm, two grasping plates rotatably connected to the first robotic arm, and a second driving member for driving the grasping plates to rotate. The number of the second driving members is the same as the number of the grasping plates, and the second driving members correspond to the grasping plates one by one. The second driving members are connected to the first robotic arm. One end of the first robotic arm is connected with a suction cup, and the suction cup is located between the two grasping plates.

[0024] By adopting the above technical solution, the second driving member drives the corresponding grasping plate to rotate, so that the grasping plate clamps the installation box. The grasping plate ensures the stability during grasping and reduces the risk of shaking or falling off. During the process of clamping the installation box, the suction cup sucks the installation box, provides a firm grasping force, prevents the installation box from sliding or falling during movement, can effectively reduce the vibration during operation, ensures the stable movement of the installation box, provides an additional guarantee to prevent the installation box from accidentally falling, and ensures the safety of operation.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The entire production process is integrally designed from bristle treatment to handle assembly and then to box screening, significantly reducing production costs and improving production efficiency.

[0026] 2. When the bristles after glue injection move to the second lifting assembly, the second lifting assembly drives the placement box to rise, so that the placement box is separated from the transmission mechanism, the clamping mechanism clamps the placement box, and the first driving member drives the rotating plate to rotate, that is, the placement box swings, so that the glue in the bristles is dispersed, improving the adhesion effect between the bristles and between the bristles and the iron sheet.
